"These ought to work the trick, sir," he remarked. "Scotland Yard will no doubt be able to identify the criminals. It's my belief that they are not fishermen but cracksmen well known to the Yard. You'll hear from us before very long, sir, I don't doubt."

Mr. Armitage made no audible comment. Personally he was not at all anxious to have to spoil his lads' holiday by attending police courts and the assizes. Mentally he decided to hurry up matters as far as the Paris trip was concerned, since there were witnesses sufficient to prove the culprits' guilt without the Sea Scouts being called upon to give evidence.

At noon the Olivette cast off and proceeded on the last stage of her homeward voyage. It was now blowing steadily from the sou'-west'ard, and with a fair tide outside the harbour the run seemed likely to be quickly performed.

With the last of the ebb the Olivette made short work of the distance between Poole Quay and the Bar Buoy; then starboarding helm, shaped a course to pass a mile to the south'ard of Christchurch Ledge.

Exactly two hours after leaving Poole, the staunch little craft arrived at her moorings in Keyhaven Lake.

"Now, lads," said Mr. Armitage, "the sooner we make a proper start the better. It will take us the rest of to-day and the whole of to-morrow to get ready for our cross-Channel trip. You know your respective duties, so 'get on with it', as the Service saying goes. By the by, Hepburn, you're steward. There's one thing I want to remind you about. Don't take too many boxes of matches, or we may have trouble with the douaniers on the other side. Matches are taxable articles in France."

During the afternoon Mr. Armitage cycled over to Lymington to obtain the necessary clearance papers from the Customs, and to collect a bundle of charts and sailing directions for the French coast lent him by a yachting acquaintance.

In their Scoutmaster's absence the Sea Scouts toiled hard, for there was a lot to be done before the interrupted refit of the Olivette was accomplished. Fresh water, fortunately, they had in plenty, but the paraffin- and oil-tanks required replenishing, and there was a considerable amount of spare gear to be brought down from the store.

That night Stratton, Roche, and Bruin were to sleep on board. In view of previous events the Patrol Leader decided to take no risks of another postponement.

After supper Peter and Roche took Bruin ashore for a run, and on the quay they encountered old Boldrigg.
