Warning: This article contains spoilers for Season 2, Episode 3, “P Is for Poison.”

The second season of Black Doves reaches its halfway point with a conspiracy that begins to connect Reed’s (Sarah Lancashire) past, Helen’s (Keira Knightley) clandestine activities, and the murders Sam (Ben Whishaw) has been forced to commit. The third episode, “P Is for Poison,” also deepens a contradiction that is becoming increasingly important: while Helen will do practically anything to preserve her life as a spy, Sam is beginning to question whether that same life is worth so many sacrifices.

After killing Jerry, the hotel concierge with whom he had begun developing a relationship, Sam is emotionally devastated. Helen, however, remains focused on investigating Wildflower and the possibility of rescuing Reed, without fully understanding the price her friend is paying to protect her. The difference between them becomes increasingly evident as events unfold, especially when we discover that someone is using Sam’s loyalty as a weapon against the Black Doves themselves.

Helen Searches for Answers and Involves Dani

Helen decides to break into the apartment of Dani (Agnes O’Casey), Wallace’s former assistant, to persuade her to help access the Black Doves’ files. The proposal understandably does not appeal to Dani, who seems particularly uninterested in becoming involved in another clandestine operation, but she eventually agrees after Helen insists.

The plan involves a special contact lens that allows Helen to monitor what Dani sees while searching for information about Wildflower. The sequence once again demonstrates the ease with which the series transforms espionage into comedy, particularly when Dani is forced to improvise in front of people who should never have found her there.

The search fails to produce the expected results because the Wildflower file is empty. Matters become more complicated when Robert Conteh (Babou Ceesay) appears and begins asking questions about Reed. Dani manages to conceal her intentions, but the conversation allows Helen to discover that the organization knows where her former handler is being held.

Dani also makes it clear that her assistance was not free and that Helen now owes her a favor. It seems like an innocent enough observation, but it carries considerable significance in a series where almost every relationship eventually becomes some kind of negotiation.

Sam Receives Another Assignment and Begins Questioning Helen

Sam seeks refuge at Lenny Lines’s (Kathryn Hunter) home after murdering Jerry because he cannot bear the thought of returning to the hotel and walking past the reception desk where the young man worked. Lenny offers him somewhere to stay, although she imposes conditions and takes away his gun, displaying a degree of concern that contrasts with her usual harshness.

The following morning, Patrick (Sam Riley) arrives to announce the next target and explain the motivations of the organization he represents. According to him, Kestrel intends to destroy the Black Doves because it considers the existence of an espionage network devoted to selling information a threat that must be eliminated.

Patrick also challenges Sam’s moral reasoning, arguing that he places a higher value on Helen’s life than on those of the people he kills to protect her. It is an especially cruel provocation after Jerry’s murder, but one that forces Sam to confront a contradiction that has followed him since the first season.

Sam does not seem convinced that Kestrel’s objectives are necessarily noble, but he begins to show increasingly obvious resentment toward the Black Doves and Helen herself. He accepts the new contract and discovers that he must assassinate Alexi Chernov (Goran Kostic), the Russian diplomat connected to the old Wildflower operation.

The choice could hardly be more complicated because Helen is investigating Chernov and intends to meet him during a dinner hosted by Wallace.

Helen’s Past Begins to Raise Suspicions

While preparing to accompany her husband to his official engagements, Helen is summoned to a meeting with Jim Perryman, an MI5 officer responsible for checking aspects of her background and ensuring that the prime minister’s family does not represent a vulnerability to British national security.

The problem is that Helen has built her identity on false information, and Wallace’s position is making it increasingly difficult to prevent anyone from examining her past closely.

Perryman begins by asking questions about Helen’s parents, supposedly buried in Kenya, and wants to know the name of the cemetery where they are buried. He then mentions Bonnie Weir, identified as her half-sister, who had repeatedly attempted to contact the government to reveal their family connection.

Helen tries to maintain her composure and responds like someone accustomed to lying under pressure, but the conversation takes a more threatening turn when Perryman informs her that Bonnie died in prison about a year earlier.

The information suggests that events preceding Helen’s recruitment by the Black Doves may be about to compromise her identity. She is no longer simply trying to hide her activities as a spy from Wallace, but to prevent British intelligence from discovering that the prime minister’s wife may not be the woman she claims to be.

It is a particularly interesting development because, for the first time, the threat does not necessarily come from another assassin or a criminal organization, but from the very state security apparatus that Helen believes she can manipulate.

Helen and Sam Disagree About the Future of the Black Doves

Helen continues trying to locate Reed and once again turns to Laila (Ambika Mod), despite the difficulties they encountered in previous episodes. The mission involves capturing a member of the organization to discover where her former handler is being held.

Sam is also asked to participate, but he shows little enthusiasm for continuing to risk his life in defense of the Black Doves. Their disagreement exposes a fundamental difference in perspective, because Helen considers it important to preserve the organization that gave her an identity and a career, while Sam increasingly sees it as part of the system responsible for his own unhappiness.

For Helen, abandoning the Black Doves would mean giving up an essential part of who she believes herself to be. For Sam, continuing to work for people who treat human lives as disposable resources seems increasingly difficult to justify.

The problem is that neither can simply walk away. Helen depends on the Black Doves to sustain the life she has built with Wallace, while Sam is being blackmailed by Kestrel with a recording that could permanently compromise his friend.

When Helen mentions that she will be attending a dinner with Alexi Chernov and his wife, Katia (Sylvia Hoeks), Sam realizes that he will have an opportunity to carry out Patrick’s assignment. He conceals his intentions and approaches Williams (Ella Lily Hyland) and Eleanor (Gabrielle Creevy) to arrange the assassination.

A Diplomatic Dinner Ends in Murder

Wallace and Helen welcome Alexi and Katia Chernov to a dinner intended to contribute to diplomatic discussions ahead of an international conference organized by the British government. The Russian couple’s presence is politically sensitive, but Helen uses her influence to facilitate the meeting, despite objections from Cecile Mason (Neve Campbell), the American representative.

The gathering also interests Helen for reasons quite different from those of her husband, since she hopes to discover what the Chernovs know about Ida Povetkin’s death, Operation Wildflower, and the events in East Berlin.

While Wallace talks with his guests about international affairs, Helen takes advantage of a private moment with Katia in the bathroom to ask questions about the supposed robbery at the couple’s Paris hotel suite. She also mentions their former housekeeper’s death and tries to understand Alexi’s involvement with Soviet intelligence.

Katia offers no definitive answers, but the conversation suggests that Helen still does not know the full extent of the events she is investigating.

Meanwhile, Sam, Williams, and Eleanor arrange the assassination behind the scenes. Their strategy involves poisoning Chernov’s food, taking advantage of changes to the orders and the movements of the staff serving the guests.

Eleanor participates in the operation disguised as a waitress and helps ensure that the substance reaches the intended target. The sequence reinforces the show’s distinctive humor, as a high-level diplomatic dinner becomes an assassination operation conducted practically under the British prime minister’s nose.

The mission succeeds, and Chernov dies from the poison in his car after leaving the dinner with Wallace and Helen.

When Helen discovers that Sam has killed the very man she was hoping to investigate, she reacts furiously, particularly because he never warned her of his intentions. For the spy, Chernov’s death represents the loss of an important source of information; for Sam, it was simply another order he had to obey to protect his friend.

The Friendship Between Helen and Sam Begins to Fracture

Chernov’s death demonstrates how the two protagonists are now working toward potentially incompatible objectives. Helen wants to discover the truth about Wildflower and prevent the destruction of the Black Doves, while Sam must eliminate precisely the people who might help her achieve those goals.

The situation is even more complicated because Sam cannot fully disclose Patrick’s threats without putting Helen in danger. His loyalty remains unwavering, but it is acquiring an almost self-destructive dimension.

It is also curious to observe how Helen continues demanding transparency from her friend while keeping practically everyone around her immersed in lies. She deceives Wallace, manipulates Dani, distrusts Conteh, and relies on Sam’s abilities whenever she needs help, yet seems unable to acknowledge that he, too, is paying a price for the choices they have both made.

The series never presents Helen as an innocent character, which may be one of its greatest strengths. Her intelligence, humor, and ability to improvise make her actions understandable, although that does not necessarily make them defensible.

Reed Is Wildflower, and Sam Receives His Final Assignment

After obtaining information about Reed’s whereabouts, Helen begins preparing an operation to free her from Black Doves’ custody. The plan involves Sam and Laila, as well as the possibility of once again seeking assistance from Williams and Eleanor.

Meanwhile, Conteh receives information placing Sam and Laila among the organization’s new targets. He authorizes contracts to eliminate them, demonstrating that the Black Doves no longer make clear distinctions between former allies and potential enemies.

Laila is ambushed by a gunman near a business in London, and the episode leaves her fate uncertain, without confirming whether she has survived the attack.

Sam’s situation becomes even more complicated when Patrick reveals the identity of his final target. After killing Erik Klein, Spitfire, Jerry, and Alexi Chernov, he finally learns the identity of the person Kestrel most wants dead.

The name is Reed, identified as Wildflower.

The revelation changes our interpretation of everything that has happened so far, demonstrating that the East Berlin operation is directly connected to Helen’s former handler and that the assassinations were probably arranged to reach someone who knows compromising details about the past.

The problem is that Sam has just agreed to participate in Helen’s mission to rescue Reed. He will have to accompany his friend to the place where the woman is being held, while his employers expect him to carry out the order to kill her.

The Conspiracy Begins to Threaten the Protagonists’ Friendship

The third episode of Black Doves makes it clear that the Kestrel mystery is not simply connected to an old espionage operation, but also to an attempt to destroy the relationships sustaining the organization. By hiring Sam to eliminate agents and finally ordering Reed’s death, Patrick has turned the assassin’s loyalty to Helen into a weapon against the Black Doves themselves.

The contradiction is especially cruel because Sam does not necessarily want to protect the organization. Helen has always been his priority, but the two objectives are becoming incompatible, since preserving his friend may require destroying people who are fundamental to the life she has built.

Helen, meanwhile, faces threats from every direction. Her marriage to Wallace remains marked by distrust, MI5 has begun investigating her past, and her superiors no longer seem willing to allow her to conduct operations independently. The position that should have made her one of the Black Doves’ most valuable agents has also turned her into a particularly vulnerable target.

The series continues exploring these contradictions with humor, although events are beginning to have increasingly serious consequences. The ease with which Sam and Eleanor manage to assassinate a diplomat during an official dinner is almost absurd, but it demonstrates how the apparently orderly world of political institutions can be infiltrated by characters who recognize virtually no moral boundaries.

At the same time, the revelation that Reed is Wildflower shifts the center of the conspiracy toward a character whose history remains surrounded by secrets. If she was the only survivor of an operation carried out decades earlier, she may possess information capable of compromising not only Kestrel but the Black Doves themselves.

The episode therefore ends with a situation that appears impossible to resolve without further betrayals. Helen intends to save Reed to discover the truth, Sam has been ordered to kill her, and the Black Doves are prepared to eliminate anyone who threatens their interests.

After sacrificing Jerry to protect Helen, Sam will have to decide how far he is willing to take that loyalty, particularly when it begins to demand not only the deaths of strangers but the destruction of the very organization his best friend wants to preserve.
