No. 16’s decoy plot

No. 16’s decoy plot is an attempted escape built around a false trail: a hospital nurse and an invalid boy are made to seem like the people carrying Tuppence away, while the conspiring woman presents herself as their victim. Its decisive weakness is practical rather than theatrical. Tommy reconstructs the five-minute interval, recognizes that the supposed sequence of disguising, drugging, binding, and escape could not have happened as described, and discovers Tuppence hidden beneath the bed coverings. The scene turns disguise from a means of disappearing into a means of directing the pursuers toward the wrong people and place.

Design and Intended Effect

The plan depends on the pursuers accepting the nurse and boy as the urgent trail. Their presence at the hotel is not improvised at the last instant: they had stayed there for a day or two, giving the hotel staff time to become accustomed to seeing them. When the nurse and her patient leave in a taxi, the apparent escape acquires a concrete, observable endpoint. That visible departure is precisely what makes the decoy useful: it offers investigators a ready-made direction of pursuit, away from the room where Tuppence has actually been concealed.

The accompanying story assigns the woman a second role. She is supposed to appear as someone gagged and bound by accomplices, a pitied victim rather than a participant in the plot. Tommy had initially swallowed the account, and its effectiveness rests on this inversion: the apparent captive is part of the scheme, while the person whose whereabouts matter most is hidden from view. The plan therefore manipulates not only clothing and identity but also the investigators’ assumptions about who needs rescue and which departure deserves attention.

The Exit and the False Trail

After checking the hotel, the investigators learn that the nurse and her patient had driven away about five minutes earlier. The departure is real, but its meaning is false: it confirms that the decoy party has left, not that Tuppence has escaped with them. The timing becomes the clue. Tommy recalls that the supposed nurse and the disguised woman must have passed a waiter in the passage just before he and his companions came up in the lift, leaving the plot with an exceptionally narrow interval in which to perform its claimed sequence.

The route was also prepared through concealment and costume. In the room, Tommy finds a small rolled bundle of black clothes under the sofa. Unrolled, it reveals the long black coat Tuppence had worn that day, her walking dress and hat, and a long fair beard. The bundle makes the manipulation of appearance tangible: clothing is evidence of a planned change of identity, not merely a disguise noticed after the event. Tommy concludes that the Russian had dressed Tuppence in boy’s clothes and altered his own appearance before walking out openly, while the nurse and boy provided the more conspicuous trail.

Tommy’s Reconstruction

Tommy’s first reconstruction gives the apparent escape its frightening shape. He thinks the conspirator silenced the woman in the adjoining room and Tuppence, moved Tuppence into the room, changed her clothes, and left with her disguised as a boy. He suspects the clothes had been hidden in advance and that the man exploited the possibility that the neighboring room would be empty. At this stage, he also cannot explain how Tuppence could have cooperated. The missing explanation matters because it shows that the visible costume and the assumed escape route do not account for Tuppence’s condition or location.

He then re-examines the account through sequence and physical feasibility. The story requires the conspirators, in only five minutes, to drug Tuppence, dress her in boy’s clothes, gag and bind another woman, and change the woman’s appearance, all while setting up the nurse-and-invalid departure as a decoy. Tommy judges that this is physically impossible in the time available. The deception has worked by distributing attention across several dramatic actions; his correction comes from putting them back into chronological order and refusing to treat the story as a single, seamless performance.

Discovery and Significance

Tommy identifies the woman’s supposed victimhood as a role and orders her removed from the bed. Beneath the coverings and bolster, Tuppence lies horizontally across the top of the bed, her eyes closed and face waxen. The sight brings Tommy a moment of dread; then he sees her breast rise and fall. She is drugged, not dead. That small bodily sign resolves the immediate uncertainty while showing the cost of the plot: Tuppence has been rendered helpless, and the staged escape has come close to turning a search into a fatal misunderstanding.

The decoy’s failure is consequently also a demonstration of the Beresfords’ method. The false nurse-and-invalid trail exploits familiar expectations about hotel guests, medical care, and a woman apparently needing help; the hidden costume bundle and the precise passageway timing supply clues that can be tested against those expectations. Tommy does not defeat the scheme simply by guessing who is disguised. He separates what was seen—the taxi’s departure and the woman’s apparent restraints—from what those appearances were intended to mean, then tests the proposed actions against time, space, and bodily possibility. The plan’s theatrical logic collapses under that practical accounting.
