"To which of the two do you attach the greater importance?" was Wingate's next question. "It is hard to say. But by following both we may arrive at a solution. They must be pursued simultaneously and that requires two men. Personally I think the Bellamy track may produce the better result, and naturally I should like to choose that for myself. On the other hand, the Wrenwyck one requires some experience and _finesse_, both of which qualities I flatter myself I possess. Anyway, I must trust one of the two to a subordinate." He passed, and remained silent for a few moments, then made up his mind. He rang the bell, and requested that Johnson should come to him at once. "I have resolved to take the Bellamy clue," he explained to Wingate. "It will require some research, possibly lengthy communications with the police of other countries. Here I shall be better equipped than a comparatively new man. Johnson has so far acted with great promptitude in the Wrenwyck matter." Detective-sergeant Johnson appeared almost immediately, and to him Smeaton issued brief instructions. "About Lady Wrenwyck. You have lost no time over this, and I want you to follow it up. This is Mr Wingate, before whom we can speak quite freely. Find out where the lady is and, equally important, if she is alone, or with a companion. I exclude, of course, her maid." Mr Johnson bowed. "I quite understand, sir. I know, as a fact, her maid left with her. She was with her ladyship before her marriage, and is, no doubt, entirely in her mistress's confidence." The detective paused a second, and then added a little touch of his own which, he was sure, would not be lost on his chief. Besides, it showed his knowledge of high society, and of the ways of ladies who were a trifle unconventional. "Of course, sir, in circumstances of a delicate nature, ladies have been known to give their maids a holiday." "I quite appreciate that point, Johnson. Well, get on to the job at once, and confer with me when necessary." Johnson withdrew, well pleased that his chief had entrusted him with so important a mission. Smeaton turned to his visitor. "Well, Mr Wingate, we ought to find out something in the next few days. I will get on to the track of Bellamy at once. Kindly drop a note to Boyle that I will keep his letters for a little time. Good-bye for the present. I will communicate with you the moment there is anything worth telling." He set to work at once on the Bellamy _dossier_. Up to a certain point the task was comparatively easy. The man was of Polish origin, his real name being Ivan Bolinski. A little further investigation revealed the fact that he was the elder brother of the Bolinski who lived in the Boundary Road, St John's Wood, the man who had dined with Monkton at the Soho restaurant, and according to the evidence of Davies, the taxi-driver, one of the pair who had hailed his vehicle for the conveyance of the dying man to Chesterfield Street.
