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. He was not altogether surprised to find that the Assistant Commissioner in charge of the Criminal Investigation Department, and Winter the Chief Constable, were there to greet him. They had run down by car--a little too late for the fair as Winter expressed it. They listened as he gave a short account of the events of the day, and Winter chuckled as Labar told how he had fallen into Larry's trap and extricated himself. "You came close to making a hash of it, young feller. You wouldn't have any sympathy from me if you were a corpse right now. You're too darned impetuous. I've told you so before. Besides, what business had you running things on your own? You're an outsider in this district. You might have paid the local officers the compliment of consulting them before you dashed off on this stunt. You didn't even have the excuse that Miss Noelson was still here." "I agree, sir," said Labar with the complacency of a man who felt that results had justified him. "I was wrong." "Well, don't let it happen again, that's all. Running round bossing everybody just as if you were Home Secretary, instead of a chief detective inspector." Labar lifted his eyebrows. "I beg your pardon, sir." The Assistant Commissioner broke in. "That's Winter's way of keeping you humble, Mr. Labar. It's quite true that you are promoted. It will be in orders this week." "Can't trust you in a division," snorted Winter. "Want to have you under my own eye at the Yard. I'll see that you work." He broke off abruptly with a comment on the escape of Larry Hughes and thus sidetracked any attempt at thanks on the part of Labar and brought him back to the business in hand. The two Yard chiefs elected to take a hand in the search of the tunnel. "How did it come about that you thought of a back door?" asked the Assistant Commissioner.
