can't
communicate with--his guardian--till the post office opens to-morrow. On
condition that Lady Scarlett is released _to-night_, however, and _only_
on that condition, I will guarantee that the boy shall be with you by
ten-thirty A. M. Meanwhile, you can be packing to clear out of Dun Moat,
as I hardly think you'll care to claim your niece's hospitality longer,
in the circumstances."

"We have no money!" the woman choked.

"You've forgotten what you took from Lady Scarlett. And six weeks'
advance of rent paid you by Captain Burns: twelve hundred pounds. He'll
forget, too, if you offer the right inducement. You could have had more
from him, if you hadn't insisted on the clause leaving you free to turn
your tenant out at a fortnight's notice after the first month. I
understand _now_ why you wanted it. If the girl had signed her name to a

The woman started. "What are you doing that for?" she jerked.

"I wish to order the taxi to take us to Dun Moat," I explained. "I
confess I'm not so fond of your society that I'd care to walk a mile

you'd be two against one. And you might hold me up----"

"As you've held us up!" the man snapped.

"Exactly," I agreed.

Wolves in sheep's clothing have to behave like sheep when they're in
danger of having their nice white wool stripped off. No doubt this is
the reason that, when we arrived at the outside entrance of the
bachelor's wing, my companions were meek as Mary's lamb.

Inside the suite of the garden court we found Terry Burns and his man
raging, and Kramm sulking, in a room with a broken window. Terry had
smashed the glass in order to get in, but his search had been vain. To
do the old servant justice, she had the instinct of loyalty. I believe
that no bribe would have induced her to betray her mistress. It remained
for the Scarletts to give themselves away, which they did--with the
secret of the room under the twisted chimney.

The room was built into the
