The door of Mr. Devereux's office was marked "Enter," and the newcomers found themselves in a small but comfortably furnished room. At a round polished table, on which there was a typewriting machine, sat a young lady, who was reading a novel of Miss Marie Corelli's.

"Mr. Devereux is in," she said in answer to their queries, "but he is just about to leave. However, I will take your name and see if he can see you."

Some people would have been annoyed at this fashion of greeting, but to the two simple gentlemen in question it seemed quite right and proper that such a rare bird as an American handwriting expert should be fenced round with a certain ritual.

"Tell Mr. Devereux," said Lord Ellerdine, "that Lord Ellerdine is here. Mr. Devereux knows me."

Unlike the young person in the café, the young lady in the office did not seem at all impressed, but languidly sauntered through the door which led to the inner room. She came back much more quickly than she had entered. "Mr. Devereux begs that you will step in," she said, and once more fell to her enthralling romance as the door closed behind the visitors.

Mr. Devereux was a well-dressed, trim young American with a hard, clean-shaved face. His manner was brisk, business-like, and deferential, and his whole appearance suggested energy and capability.

Upon his large leather-covered writing-table were various appliances used in his business.

One saw a microscope of some peculiar construction. There were a variety of small lenses and reading-glasses, together with various instruments of shining steel for measuring, with extreme accuracy, the length of a letter or a line.

There was also an enlarging camera upon a shelf by the window, and a door in one corner of the place was marked "Dark room."

"Glad to see you again, my lord," said Mr. Devereux. "Not a forgery case this time, I hope?"
