“Any person who positively remembers passing through Waverley Avenue between N and M Streets on the evening of May the eleventh at or near the hour of a quarter past seven will confer a favor on the detective force of the District by communicating the same to F. at the police headquarters in C street.”
I was “F.,” and I was soon deep in business. But I was readily able to identify those who came from curiosity, and as the persons who had really fulfilled the conditions expressed in my advertisement were few, an evening and morning’s work sufficed to sift the whole matter down to the one man who could tell me just what I wanted to know. With this man I went to the major, and as a result we all met later in the day at Mr. Moore’s door.
This gentleman looked startled enough when he saw the number and character of his visitors; but his grand air did not forsake him and his welcome was both dignified and cordial. But I did not like the way his eye rested on me.
But the slight venom visible in it at that moment was nothing to what he afterwards displayed when at a slight growl from Rudge, who stood in an attitude of offense in the doorway beyond, I drew the attention of all to the dog by saying sharply:
“There is our witness, sirs. There is the dog who will not cross the street even when his master calls him, but crouches on the edge of the curb and waits with eager eyes but immovable body, till that master comes back. Isn’t that so, Mr. Moore? Have I not heard you utter more than one complaint in this regard?”
“I can not deny it,” was the stiff reply, “but what—”
I did not wait for him to finish.
“Mr. Correan,” I asked, “is this the animal you gassed between the hours of seven and eight on the evening of May the eleventh, crouching in front of this house with his nose to the curbstone?”
“It is; I noted him particularly; he seemed to be watching the opposite house.”
Instantly I turned upon Mr. Moore.
