As the gentleman at the door, who was none other than Mr. Gorby, did not hear her, he of course did not reply, so she hurried down the stairs, crackling with anger at the rough usage her bell had received.

Mr. Gorby had seen Brian go out, and deeming it a good opportunity for enquiry had lost no time in making a start.

"You nearly tored the bell down," said Mrs. Sampson, as she presented her thin body and wrinkled face to the view of the detective.

"I'm very sorry," answered Gorby, meekly. "I'll knock next time."

"Oh, no you won't," said the landlady, tossing her head, "me not 'avin' a knocker, an' your 'and a-scratchin' the paint off the door, which it ain't been done over six months by my sister-in-law's cousin, which 'e is a painter, with a shop in Fitzroy, an' a wonderful heye to colour."

"Does Mr. Fitzgerald live here?" asked Mr. Gorby, quietly.

"He do," replied Mrs. Sampson, "but 'e's gone out, an' won't be back till the arternoon, which any messige 'ull be delivered to 'im punctual on 'is arrival."

"I'm glad he's not in," said Mr. Gorby. "Would you allow me to have a few moments' conversation?"

"What is it?" asked the landlady, her curiosity being roused.

"I'll tell you when we get inside," answered Mr. Gorby.
