“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.

So far, the scent seemed a warm one. Bellamy, to give him his assumed name, was born of an English mother, and, in marked contrast to his brother, betrayed very little of the foreigner in his appearance. He spoke English with a perfect accent.

He had started his career as a money-lender, his operations, which were on a small scale, being confined chiefly to his compatriots. He next blossomed out, in conjunction with a couple of scoundrels of the same kidney, into a promoter of small and shady concerns. Success attended his efforts, and he then flew at higher game. But although he amassed money he was never connected with a single flourishing company. He made thousands out of his victims, but they never saw a penny of their money back until just at the end.
