ers wearily into a drawer and turned
the key. His speculations were unprofitable. He turned over in his brain
his plans for running down Grell. Of the people who had been assisting
him to evade capture three were out of the way for the time being. Ivan
Abramovitch and Condit were safely under lock and key. The Princess
Petrovska was out of London, and there was a fair margin of assumption
that she was located somewhere in Liverpool, where the local police were
assisting the Scotland Yard men. It was hardly possible that she would
double back, even if she evaded their rigorous search. With the
detectives on duty at the London termini reinforced and on strict watch,
her chances of doing so were very slim.

With three of his friends out of touch, and hampered by want of money,
Grell would have to seek a fresh refuge. The chief result of Foyle's
actions had been to make any steps he might take more difficult. That
was all. It was still possible for him to dodge the pursuit.

The evening papers with the story of the raid were already upon the
streets. What would be the effect upon Grell's plans when he learned
that Ivan had been captured? In the case of an ordinary criminal, Heldon
Foyle might have forecasted what would happen with a fair degree of
certainty. But Grell was not an ordinary criminal, even if he were a
criminal at all. If he could gain a hint of the possible intentions of
the fugitive he might be able to meet them.

There was a vague chance that either Ivan Abramovitch or Condit might be
induced to volunteer a statement, although the possibility was remote.
In America or France there would have been ways of forcing them to
speak. In England it was impossible.

With a yawn Foyle relinquished his efforts, and his head dropped forward
on his desk. In a little he was fast asleep. He was roused by a light
touch on the shoulder. Green had returned.

"Hello!" said the superintendent. "I must have dozed off. How have you
got on?"

Green adjusted his long body to the comfort of an arm-chair. "We found
the Chinaman. He'd climbed through a trap-door on to the roof. We went
over the house with a tooth-comb, both before and after I'd had a little
talk with Keller. It seems that both he and his partner the Chinaman had
known the man for some time before they gave him a room. They're old
hands at the game and won't talk too much. He went out very
occasionally, and mostly at night. We found nothing bearing on the
