seen him many a time, of course. Now what's he like!"
"He's a tall gentleman," said the boy, after some evidently painful thought.
"Yes, but what else—has he got a beard?" asked Viner.
"Couldn't tell you that, guv'nor, d'yer see," said the lad, "'cause he's one o' them gents what allus wears a white silk handkercher abaht his face—up to his eyes. But he's a big man—wears black clothes."
Viner gave the boy his promised reward, and was passing on when Miss Wickham touched his arm.
"Ask if he's seen a lady go out this way," she said. "That's equally important."
The boy, duly questioned nodded his head.
"I see Mrs. Killerby go out not so long since," he answered. "Her what used to live here one time. Know her well enough."
"Come along!" muttered Viner. "We've hit it! Mrs. Killerby—who is Mrs. Killenhall—used to live here at one time! Good—which means very bad, considering that without doubt the doctor who wears a white silk handkerchief about his face is the muffled man of Lonsdale Passage. Miss Wickham, something has alarmed these birds and they've flown."

"I've an idea as to why you were," said Viner, "and I propose to find out at once if I'm right.

"Here's one of Carless' clerks, and Perkwite the barrister.—What are you doing here?"
