Of one fact, however, he was certain--that diamond buckle belonged to Miss Celia Lennard, and she lived at an address in London which he had by that time written down in his pocket-book. And now arose the big (and, in view of what had happened, the most important and serious) question--how had Miss Celia Lennard's diamond buckle come to be in Room Number 263? That question had got to be answered, and he foresaw that he and Miss Lennard must very quickly meet again. But there were many matters to be dealt with first, and they began to arise and to demand attention at once. Before he had finished breakfast came a wire from Mr. Franklin Fullaway, answering his own:-- "Deeply grieved and astonished by your news. Am coming down at once, and shall arrive Hull two o'clock. In meantime keep strict guard on your cousin's effects, especially on any sealed package. Most important this should be done." This message only added to the mass of mystery which had been thickening ever since the early hours of the morning. Strict guard on James's effects--any sealed package--what did that mean? But a very little reflection made Allerdyke come to the conclusion that all these vague references and hints bore relation to the possible transaction mentioned in the various telegrams already exchanged between James Allerdyke and Franklin Fullaway, and that James had on him or in his possession when he left Russia something which was certainly not discovered when Gaffney searched the dead man. There was nothing to do but to wait: to wait for two things--the result of the medical investigation, and the arrival of Mr. Franklin Fullaway. The second came first. At ten minutes past two a bustling, quick-mannered American strode into Marshall Allerdyke's private sitting-room, and at the instant that the door was closed behind him asked a question which seemed to burst from every fibre of his being-- "My dear sir! Are they safe?" CHAPTER V THE NASTIRSEVITCH JEWELS
