Brigid O’Shaughnessy–Floyd Thursby alliance

Brigid O’Shaughnessy and Floyd Thursby’s alliance is a temporary partnership formed around the Maltese Falcon and undone by competing loyalties and broken promises. Thursby is at once Brigid’s protector and a rival who means to deny her a share; their breach leaves her seeking Sam Spade’s help, while Gutman’s group treats Thursby’s loyalty as an obstacle to be removed. The relationship links the Falcon’s pursuit to the murders surrounding it, but never becomes a stable or trusting partnership.

Formation and purpose

Brigid tells Spade that she met Thursby in the Orient and came with him from Hongkong to San Francisco. She says that he had promised to help her, but had used her dependence on him to betray her. Her account presents the alliance as something she entered from a vulnerable position, not as an equal arrangement whose terms she could control.

The immediate purpose of the partnership was to obtain a black, polished bird, about a foot high, which Brigid describes as a hawk or falcon. She says she was promised five hundred pounds for helping Cairo and Thursby get it from a Russian named Kemidov. She does not explain the method they used against Kemidov, insisting that it is not relevant to Spade’s inquiry. The value of the object is clear from the promised payment, even though Brigid says the men never told her why it mattered.

Unequal promises and the break

According to Brigid, the original arrangement collapsed when they discovered that Cairo meant to desert the others with the Falcon. She says she and Thursby acted against Cairo first, rather than let him leave them with nothing. This episode shows the alliance operating as a shifting contest among participants: cooperation lasts only while each believes the others will honor their claims to the prize.

Brigid says Thursby then promised her seven hundred and fifty pounds, but she learned by the time they reached San Francisco that he had no intention of paying. He proposed going to New York, selling the Falcon there, and giving her a share; she judged this promise untrustworthy. Her complaint is not simply that Thursby concealed information, but that the promised division of the reward had become another means of keeping her dependent on him. She approached Spade to discover where the Falcon was so she could bargain with Thursby from a stronger position.

Protection, surveillance, and suspicion

Brigid describes Thursby as someone who lived by guns. In Hongkong, she had heard a story that he had arrived in the Orient as bodyguard to a gambler who had left the United States and later disappeared; she does not claim to know whether Thursby knew what happened. What she says she knows is that he carried weapons and took precautions against anyone entering his room unnoticed, covering the floor around his bed with crumpled newspaper. These details make his protection inseparable from suspicion and danger.

Brigid wanted Spade and Miles Archer to watch Thursby because she did not know where he stayed or what he was doing. She says she wanted to learn how far he had gone, whom he was meeting, and what he intended. At the same time, she explains that Thursby’s assistance was necessary to her plan: she says she would have accepted a man of his kind as a partner if he had remained loyal. The alliance therefore contains a sharp contradiction. She depends on the very man whose movements she wants investigated.

The murders and the rival plot

Brigid says that on the night Archer was killed, she arranged for Thursby to meet her at a hotel, hoping Archer would see him. After supper and dancing at a restaurant on Geary Street, she and Thursby returned at about half past twelve. Thursby left her at the door; from inside, she watched Archer follow him down the street. Her account places Thursby on the route Archer took that night, but does not establish that Thursby killed him.

The physical and police evidence strengthens the suspicion against Thursby without making his role in Archer’s death part of Brigid’s account. Archer was found below a broken section of fence, and Spade reconstructed the shooting as a shot fired with Archer’s back to the fence, sending him through it and down the slope. Later, Tom Polhaus states that the bullet came from Thursby’s Webley-Fosbery revolver and says a bellhop had seen that distinctive weapon in Thursby’s hotel room the morning Archer died. The weapon and the route connect the two men to the murder investigation; Brigid’s reported sighting explains why Archer followed Thursby, while the available evidence leaves the precise circumstances of the shooting to the investigation.

Thursby’s protection of Brigid also makes him a target in the wider Falcon conflict. Gutman later admits that his group regarded Thursby as a notorious killer and Brigid’s ally. Gutman says the group expected Thursby’s removal to make Brigid reconsider her quarrel with them, and to leave her without so violent a protector. He further explains that his group did not think Thursby possessed the Falcon: they knew Brigid had given it to Captain Jacobi in Hongkong to be carried aboard the Paloma while she and the others took a faster boat. Gutman’s account recasts the alliance as a tactical weakness that his group deliberately exploited.

The alliance’s aftermath

The alliance’s breakdown does not free Brigid from the other players. In Gutman’s account, after Wilmer had located Thursby, Gutman tried to negotiate with him directly. Thursby remained loyal to Brigid, refused the proposed arrangement, and was then followed back to his hotel by Wilmer. This account explains why Gutman’s group treated Thursby’s attachment to the alliance as an obstacle, rather than as a route to recovering the Falcon through agreement.

The Falcon’s route further exposes how incomplete Brigid’s control of the partnership was. She had arranged for Jacobi to carry the object from Hongkong, and Jacobi later brought it to San Francisco; meanwhile, Gutman’s party pursued Brigid and Thursby without knowing that Thursby was not the one who knew where the Falcon was. Brigid’s alliance with Thursby thus did not give her secure possession of the object or reliable control over its sale. Its consequences are a widening circle of suspicion, a murder investigation tied to Thursby’s distinctive gun, and Gutman’s effort to isolate Brigid by removing her ally.

Significance

The relationship changes from cooperation into a struggle over information, money, and protection. Brigid’s story gives Thursby a double position: he is the partner who promised to help her, and the man she believes intends to cheat her. Gutman’s later explanation adds another layer, showing that Thursby’s loyalty to Brigid was recognized and used against them. The partnership is therefore not a secure bond but a temporary alignment within a larger contest, where each promise creates leverage and each shift in possession or allegiance changes who is exposed.
