urgent
and necessary investigations--the slightest disturbance, the jar
of a door--I must ask you--"

"Certainly, sir. You can turn the lock if you're like that, you
know. Any time."

"A very good idea," said the stranger.

"This stror, sir, if I might make so bold as to remark--"

"Don't. If the straw makes trouble put it down in the bill." And he
mumbled at her--words suspiciously like curses.

He was so odd, standing there, so aggressive and explosive, bottle
in one hand and test-tube in the other, that Mrs. Hall was quite
alarmed. But she was a resolute woman. "In which case, I should
like to know, sir, what you consider--"

"A shilling--put down a shilling. Surely a shilling's enough?"

"So be it," said Mrs. Hall, taking up the table-cloth and beginning
to spread it over the table. "If you're satisfied, of course--"

He turned and sat down, with his coat-collar toward her.

When she returned the room was silent again, save for the faint
crepitation of his chair and the occasional clink of a bottle.
It was all over; the stranger had resumed work.

When she took in his tea she saw broken glass in the corner of the
room under the concave mirror, and a golden stain that had been
carelessly wiped. She called attention to it.

"Put it down in the bill," snapped her visitor. "For God's sake
don't worry me. If there's damage done, put it down in the bill,"
and he went on ticking a list in the exercise book before him.

"I'll tell you something," said Fearenside, mysteriously. It was
late in the afternoon, and they were in the little beer-shop of
Iping Hanger.

"Well?" said Teddy Henfrey.

"This chap you're speaking of, what my dog bit. Well--he's black.
Leastways, his legs are. I seed t
