"I am sure he would be very much disturbed if he knew your opinion," was the faintly sarcastic reply. "He happens to be a young man with exceptionally good credentials." "Credentials," Crawshay observed blandly, "in which I have no faith--no faith whatever." The captain turned his head suddenly. There was a new expression in his face as he looked keenly at his visitor. "What do you mean, Mr. Crawshay?" "Nothing much. I see you have been smoking a pipe, Captain. You will forgive me if I light one of these perfectly damnable cigarettes which are all I have been able to buy on board.--Thank you.--I talk better when I smoke." "It seems to me that you talk a great deal of nonsense," the captain declared bluntly. "Intermingled at times," the other insisted, "with a word or two of sense. Now I am going to repeat that I have very little faith in this wireless operator of yours. At three o'clock this morning--I don't wish to tie myself down, Captain, so I will say in the vicinity of that hour--he received a message--a long one, I should imagine. I put it to you, sir--was that dispatch for you?" "No," the captain admitted, "I had no message at that hour or since." "Very-well, then," Crawshay continued, loosening a little muffler at his throat, "I suppose you can ascertain from the purser if any message was delivered to any one of your passengers?" "I certainly can," the captain admitted, "but to tell you the truth, sir, I scarcely see how this concerns you." "I am endeavouring," his visitor replied, with a little wave of his hand, "to justify my statement. Enquire of the purser, I beg you. It will do no harm." The captain shrugged his shoulders, touched the bell and despatched his steward for Mr. Dix, the purser, who, happening to be on the deck outside, made an immediate appearance. "Mr. Dix," the captain asked him, "can you tell me if you have received any wireless message intended for any one of the passengers at or since three o'clock this morning?" "Not one, sir." Crawshay's smile was beatific and triumphant. He relit his cigarette which had gone out, and, crossing his legs, made himself a little more comfortable. "Very well, then," he said, "what I should like to know is, what became of that message which made very pretty illuminations around your conductor, or whatever you call it, for at least a quarter of an hour this morning?" "The message may merely have been an intercepted one," the purser pointed out. "It may not have been fur us at all." "I had an idea," Crawshay persisted, with bland and officious precision, "that even intercepted messages, especially in time of war, were referred to some person of authority on board. Apart from that, however, the message I refer to was written down and delivered to one of your passengers. I happened to see your operator leave his office with an envelope in his hand." "At three o'clock in the morning?" the captain observed incredulously.
