"You may have noticed," he continued, "that Karamaneh's room is directly below your own. In the event of any outcry, you would be sooner upon the scene than I should, for instance, because I sleep on the opposite side of the ship. This circumstance I take to be the explanation of the wireless message, which, because of its hesitancy (a piece of ingenuity very characteristic of the group), led to your being awakened and invited up to the Marconi deck; in short, it gave the would-be assassin a better chance of escaping before your arrival." I watched my friend in growing wonder. The strange events, seemingly having no link, took their place in the drama, and became well-ordered episodes in a plot that only a criminal genius could have devised. As I studied the keen, bronzed face, I realized to the full the stupendous mental power of Dr. Fu-Manchu, measuring it by the criterion of Nayland Smith's. For the cunning Chinaman, in a sense, had foiled this brilliant man before me, whereby if by naught else I might know him a master of his evil art. "I regard the episode," continued Smith, "as a posthumous attempt of the Doctor's; a legacy of hate which may prove more disastrous than any attempt made upon us by Fu-Manchu in life. Some fiendish member of the murder group is on board the ship. We must, as always, meet guile with guile. There must be no appeal to the Captain, no public examination of passengers and crew. One attempt has failed; I do not doubt that others will be made. At present, you will enact the role of physician-in-attendance upon Karamaneh, and will put it about for whom it may interest that a slight return of her nervous trouble is causing her to pass uneasy nights. I can safely leave this part of the case to you, I think?" I nodded rapidly. "I haven't troubled to make inquiries," added Smith, "but I think it probable that the regulation respecting closed ports will come into operation immediately we have passed the Straits, or at any rate immediately there is any likelihood of bad weather." "You mean--" "I mean that no alteration should be made in our habits. A second attempt along similar lines is to be apprehended--to-night. After that we may begin to look out for a new danger." "I pray we may avoid it," I said fervently. As I entered the saloon for breakfast in the morning, I was subjected to solicitous inquiries from Mrs. Prior, the gossip of the ship. Her room adjoined Karamaneh's, and she had been one of the passengers aroused by the girl's cries in the night. Strictly adhering to my role, I explained that my patient was threatened with a second nervous breakdown, and was subject to vivid and disturbing dreams. One or two other inquiries I met in the same way, ere escaping to the corner table reserved to us.
