The man slowly turned a pair of dull-looking eyes full on Leonard. Yet it was evident that the owner of those dull-looking eyes was accustomed to reading character and forming prompt conclusions. He withdrew his gaze after a moment, and said:

“Second story. Inquire for Mr. Stark.”

He then turned to his work again, and was apparently oblivious of his surroundings.

Leonard proceeded as directed, and found Mr. Stark alone in a small room. The room was compact, neat, and orderly in appearance. On one side was a telegraphic apparatus, and on the other was a desk, surmounted by a case of pigeon-holes, containing letters and papers tied up in bundles. There was a couch and two chairs in the room. One window looked upon the street, and a closed door concealed an adjoining apartment.

Mr. Stark was a man small in stature and unpretending in aspect. His face was smooth, with thin lips, a firm-set mouth, and cool, gray eyes. He was dressed with neat precision.

“Mr. Stark?” inquired Leonard.

“Yes, sir.”

“You are, I believe, connected with the secret detective service.”

“I am.”

“Can I confer with you in reference to engaging your services?”
