Floyd Thursby

Floyd Thursby is Brigid O’Shaughnessy’s ally, a man she says betrayed her after their journey from Hong Kong, and a target in the struggle over the falcon. His killing follows Miles Archer’s murder and becomes a central pressure point in Sam Spade’s investigation: the two deaths entangle Brigid, the rival hunters, and the police, while Thursby’s allegiance and movements help expose the competing plans behind the case.

Introduction and Connection to Brigid

Brigid’s first account presents Thursby as both her recent companion and the person who has cut her off from information. She says they had come from Hong Kong the previous week and that he had promised to help her, but then took advantage of her dependence on him and betrayed her. She cannot yet explain the precise nature of that betrayal. What she does make clear is that Thursby concealed where he was staying and would not tell her what he was doing or whom he was meeting; she therefore wanted him shadowed to discover how far he had gone.

Her concern about Thursby begins amid a separate failure of communication. Brigid had written to Corinne, asking her to meet at the St. Mark, and waited three days without receiving a visit or message. With General Delivery as her only address for Corinne, Brigid returned to the post office the next day and waited until after dark. She did not find Corinne, but she did see Thursby. He would say only that Corinne was well and happy, an assurance Brigid distrusted because it came from the man whose actions she could not verify. In this first account, Thursby is an information bottleneck: he stands between Brigid and the person she is trying to reach, while refusing to disclose what he knows.

The Tail and the Two Murders

Spade tells the police that Miles Archer had been assigned to follow Thursby, describing the man as Brigid had described him. Brigid later supplies a precise account of how Archer came to follow him. Thursby arrived at her hotel at nine o’clock; she went walking with him, deliberately suggesting the outing so Archer could observe him. They stopped at a restaurant on Geary Street for supper and dancing, then returned to the hotel at about half-past twelve. Thursby left Brigid at the door. From inside, she watched Archer follow him down the street on the opposite side, in the direction of Market Street.

Brigid’s account makes her role in Archer’s surveillance explicit, but she also gives Spade an immediate conclusion about the killing: when asked whether Thursby had killed Archer, she answers yes. Spade points out that Thursby carried a Luger in a shoulder holster and that Archer had not been shot with a Luger. The distinction leaves the accusation in tension with the weapon evidence rather than resolving who killed Archer; it also makes Thursby’s own later death part of a wider puzzle, not a simple conclusion to the pursuit.

The police report that Thursby was shot four times in the back, from across the street, as he started to enter his hotel. No one had seen the shooting, and the officers describe their account as an inference from the circumstances. Thursby was carrying a Luger in a shoulder holster, but it had not been fired. The contrast between his unspent weapon and the shots from across the street separates the killing from the weapon Brigid had invoked in accusing him of Archer’s murder. His death also immediately becomes a point of suspicion for Spade: Lieutenant Dundy stresses that Thursby was killed just thirty-five minutes after Spade left Burritt Street, and Tom Polhaus adds that Spade had not stopped to look at his partner after Archer was killed. Spade answers Dundy’s confrontation sharply, but the accusation binds his movements to both deaths before the investigation has settled either one.

Thursby Within the Falcon Plot

Thursby’s significance extends beyond the pursuit that ends in his death: his shifting place in Brigid’s account and in the hunters’ plans reveals how little any participant can safely infer from apparent alliances. Brigid says that Thursby had promised to help her after they met in the Orient, but that he betrayed her while she depended on him. Later, she explains that the group’s purpose was to help obtain the falcon from a Russian named Kemidov, while refusing to tell Spade how they intended to do so. Her account establishes Thursby’s involvement in the struggle without clarifying the exact limits of his knowledge or his role in the plan.

Casper Gutman’s retrospective account complicates the picture. He says that he and his associates knew Brigid well enough not to suspect that Thursby possessed the falcon. They did not then know that she had given it to Captain Jacobi in Hong Kong to carry to San Francisco aboard the La Paloma, while she and her companions took a faster boat. Gutman says that, even if only one of them knew the falcon’s location, he did not believe that person was Thursby. The hidden transfer makes Thursby’s position in the hunt more consequential but also more limited than his association with Brigid might suggest: he was her ally, yet Gutman’s group did not regard him as the keeper of the object they sought.

Gutman also explains why his group targeted Thursby. He describes him as a notorious killer and Brigid’s ally, and says that removing him would leave her without a violent protector and might persuade her to repair her differences with Gutman’s side. Before the killing, Gutman says, he spoke with Thursby in an effort to make a deal, but Thursby remained loyal to Brigid and refused. Wilmer Cook had located Thursby two days earlier and tried to follow him to his meetings with Brigid, without success; on the night of the killing, Wilmer waited outside Thursby’s hotel, brought him to Gutman after finding him, and then followed him back. Gutman’s account thus presents the murder not as a random consequence of the falcon’s pursuit but as a failed negotiation followed by a deliberate effort to weaken Brigid’s alliance.

Death and Narrative Consequences

Thursby’s death does not settle the mystery surrounding Archer’s murder; instead, it makes the two cases harder to disentangle. Brigid names Thursby as Archer’s killer, yet the Luger he carried was not the weapon used against Archer, and it remains unfired when the police find him dead. Gutman’s account supplies a motive and a chain of action for Thursby’s killing: after Thursby rejected a deal and remained loyal to Brigid, Wilmer followed him back to his hotel. The convergence of these accounts makes Thursby both an accused killer and a victim of the same contest for allegiance and information. His removal was intended to isolate Brigid, but it also intensifies suspicion around Spade and leaves the investigation to reconstruct what each faction knew about the falcon, Archer, and the other hunters.

Narrative Function and Ethical Counterpoint

Thursby’s place in the case also clarifies why Spade treats his death as more than a clue to be sorted out. He tells Casper Gutman that a detective cannot let the killer of a partner go free: even if Miles Archer was a poor partner, the professional obligation remains, and allowing the killer to escape would damage the whole detective organization. Spade compares that obligation to a dog’s instinct to catch a rabbit, grounding his decision in professional practice rather than affection for Archer. Thursby’s death sharpens the same distinction from another angle. Brigid’s accusation makes him answerable for Archer’s murder, while Gutman’s account presents him as a man who would not abandon Brigid for a deal. Neither allegiance nor accusation alone settles what happened; together, they leave Thursby at the intersection of loyalty, violence, and the practical rules by which Spade understands his work.
