Cheyne returned to the Edgecombe, and sitting down in a deserted corner of the lounge, tried to puzzle the thing out. But the more he thought of it, the more mysterious it became. His mind up till then had been concentrated on the actual administration of the drug, and this point alone still seemed to constitute an insoluble problem. But now he saw that it was but a small part of the mystery. Why had he been drugged? It was not robbery. Though he had over £100 in his pocket, the money was intact. He had no other valuables about him, and in any case nothing had been removed from his pockets. It was not to prevent his going to any place. He had not intended to do anything that afternoon that could possibly interest a stranger. No, he could form no conception of the motive.
But even more puzzling than this was the question: How did Parkes, if that was really his name, know that he, Cheyne, was coming to Plymouth that day? It was true that he had mentioned it to his mother and sister a couple of days previously, but he had told no one else and he felt sure that neither had they. But the man had almost certainly been expecting him. At least it was hard to believe that the whole episode had been merely the fruits of a chance encounter. On the other hand there was the difficulty that any other suggestion seemed even more unlikely. Parkes simply couldn’t have known that he, Cheyne, was coming. It was just inconceivable.
He lay back in his deep armchair, the smoke of his pipe curling lazily up, as he racked his brains for some theory which would at least partially meet the facts. But without success. He could think of nothing which threw a gleam of light on the situation.
And then he made a discovery which still further befogged him and made him swear with exasperation. He had taken out his pocket-book and was once more going through its contents to make absolutely sure nothing was missing, when he came to a piece of folded paper bearing memoranda about the money matters which he had discussed with his banker. He had not opened this when he had looked through the book after regaining consciousness, but now half absent-mindedly he unfolded it. As he did so he stared. Near the crease was a slight tear, unquestionably made by some one unfolding it hurriedly or carelessly. But that tear had not been there when he had folded it up. He could swear to it. Someone therefore had been through his pockets while he was asleep.
Chapter II.
Burglary!
The discovery that his pockets had been gone through while he was under the influence of the drug reduced Cheyne to a state of even more complete mystification than ever. What had the unknown been looking for? He, Cheyne, had nothing with him that, so far as he could imagine, could possibly have interested any other person. Indeed, money being ruled out, he did not know that he possessed anywhere any paper or small object which it would be worth a stranger’s while to steal.
Novels he had read recurred to him in which desperate enterprises were undertaken to obtain some document of importance. Plans of naval or military inventions which would give world supremacy to the power possessing them were perhaps the favorite instruments in these romances, but treaties which would mean war if disclosed to the wrong power, maps of desert islands on which treasure was buried, wills of which the existence was generally unknown and letters compromising the good name of wealthy personages had all been used time and again. But Cheyne had no plans or treaties or compromising letters from which an astute thief might make capital. Think as he would, he could frame no theory to account for Parkes’s proceedings.
He yawned and, getting up, began to pace the deserted lounge. The effects of the drug had not entirely worn off, for though he had slept all the afternoon he still felt slack and drowsy. In spite of its being scarcely ten o’clock, he thought he would have a whisky and go up to bed, in the hope that a good night’s rest would drive the poison out of his system and restore his usual feeling of mental and physical well-being.
But Fate, once more in the guise of an approaching page, decreed otherwise. As he turned lazily towards the bar a voice sounded in his ear.
“Wanted on the telephone, sir.”
