Word reached Labar at the end of the search that a suspicious yacht had been picked up by H.M. destroyer Hawk off Dungeness and had been escorted to Dover. Everything had been found in order aboard her, but that her owner’s name was given as Hughes. The crew were remaining on board under guard, until such time as someone from Scotland Yard should look them over. This was a business in which he promptly enlisted the services of Moreland, who departed with one of his sergeants in a motor car with a promise to return at the earliest possible moment. The news that the motor boat which had put out from Camber had broken down ere it reached its destination was now of trifling interest.

Satisfied, after a couple of hours, that the likelihood of picking up Larry immediately was remote, Labar returned to Mope’s Bottom with Malone and two or three more men from the Yard to make a systematic and complete rummage of the tunnel.
