Dalby’s motorcycle decoy device

Dalby’s motorcycle decoy device was a wooden attachment used to conceal the mechanics of the Tokwe framing operation. First presented as a battered contraption recovered with photographs of a motorcycle from the ocean floor, it eventually disclosed how Dalby had moved unseen by radar, arranged a witness’s death, and planted evidence near the Unnamed narrator’s car. Its recovery helped persuade the Americans that the narrator had been framed, though it did not immediately secure his freedom.

Construction and identification

The device was brought to the office by the Brigadier in two large cardboard boxes. When assembled, the chipped, faded wooden contraption measured about six feet; a red automobile light was attached at each end. The Brigadier’s photographs of a battered motorcycle dragged from the ocean floor gave the narrator the clue that connected the object to Dalby’s plan.

The wooden plank had been bolted to the back of a motorcycle. Its significance was not apparent from its appearance alone: the narrator recognized it only by recalling the object he had followed across Tokwe on the night of his arrest. The later display converted an obscure piece of equipment into an explanation for events that had previously looked like evidence against him.

Use in the Tokwe framing operation

The motorcycle was small enough not to register on radar. Dalby moved the wooden block across the road, then used HT wires to kill the only witness. He also used the High Speed TV camera and discarded it in the sea near the narrator’s car, where echo sounders would detect it. The camera’s placement made the narrator’s proximity appear incriminating, while the motorcycle and attachment allowed Dalby to leave the area by a different route.

Dalby left the road and crossed open country before dumping the motorcycle off another part of the island. The narrator understood the device as part of a coordinated deception: it helped make the movements and planted evidence seem to point toward him, while Dalby relied on wind, a good silencer, and confusion to escape. The attachment was therefore not merely transport equipment but part of the physical arrangement that made the false case plausible.

Recovery and evidentiary consequences

After the narrator’s arrest, Jean returned to the Japanese blockhouse. The cathode tube, a slip of information, and a pistol were gone, but she studied a map and worked out Dalby’s motorcycle trick. Acting on the three locations she marked, the Brigadier had them searched; the initial searches found nothing because they had not accounted for the undertow.

The motorcycle was eventually found a considerable distance out to sea, with the wooden device still attached. Dalby could not risk the attachment floating free. Its survival on the recovered motorcycle gave the Americans concrete support for Jean’s explanation, and they became convinced that the narrator had been framed. Skip Henderson was recalled to Tokwe, while Ross flew to the Pentagon; the recovery also meant that the pressure on Dalby was mounting, though it did not immediately improve the narrator’s situation.

The precise reason the motorcycle was found so far out remained unsettled. The narrator suspected Dalby had driven it at high speed toward the water to carry it as far as possible; Jean attributed its position to the undertow. The device thus supplied a decisive explanation of the deception without resolving every detail of how the motorcycle reached its final location.

Narrative significance

The device’s importance depends on a reversal in how it is seen. At first it is an unfamiliar, damaged object assembled from boxes; once connected to the motorcycle the narrator followed, its physical details make an apparently incriminating sequence intelligible as a deliberate setup. The recovered attachment gives a material trace to Jean’s deduction and helps shift the investigation’s judgment, even though the narrator remains caught in the consequences for a time.
