My plight was awkward. I certainly did not think it safe to present myself before the lady; she would undoubtedly recollect my face. Yet I had orders to detain her until the appearance of Lady Molly.

Miss Marvell seemed in no hurry. She was putting on her gloves as she came downstairs. In the hall she gave a few more instructions to the porter, whilst I, in a dark corner in the background, was vaguely planning an assault or an alarm of fire.

Suddenly, at the hotel entrance, where the porter was obsequiously holding open the door for Miss Marvell to pass through, I saw the latter’s figure stiffen; she took one step back as if involuntarily, then, equally quickly, attempted to dart across the threshold, on which a group—composed of my dear lady, of Saunders, and of two or three people scarcely distinguishable in the gloom beyond—had suddenly made its appearance.

Miss Marvell was forced to retreat into the hall; already I had heard Saunders’s hurriedly whispered words:

“Try and not make a fuss in this place, now. Everything can go off quietly, you know.”

Danvers and Cotton, whom I knew well, were already standing one each side of Miss Marvell, whilst suddenly amongst this group I recognised Fanny, the wife of Danvers, who is one of our female searchers at the Yard.

“Shall we go up to your own room?” suggested Saunders.

“I think that is quite unnecessary,” interposed Lady Molly. “I feel convinced that Mr. Leonard Marvell will yield to the inevitable quietly, and follow you without giving any trouble.”

Marvell, however, did make a bold dash for liberty. As Lady Molly had said previously, he was far too clever to allow himself to be captured easily. But my dear lady had been cleverer. As she told me subsequently, she had from the first suspected that the trio who lodged at the Scotia Hotel were really only a duo—namely, Leonard Marvell and his wife. The latter impersonated a maid most of the time; but among these two clever people the three characters were interchangeable. Of course, there was no Miss Marvell at all. Leonard was alternately dressed up as man or woman, according to the requirements of his villainies.

“As soon as I heard that Miss Marvell was very tall and bony,” said Lady Molly, “I thought that there might be a possibility of her being merely a man in disguise. Then there was the fact—but little dwelt on by either the police or public—that no one seems ever to have seen brother and sister together, nor was the entire trio ever seen at one and the same time.
