consequence reposed in an inside drawer, and these the
superintendent replaced. A footstep outside caused him hurriedly but
noiselessly to close the desk and resume his seat, sitting idly with
crossed legs. But the interrupter passed, and he returned to the desk.
From a recess he drew out a cheque-book and examined the counterfoils of
the used cheques with interest. The last counterfoil was blank.

"Ah!" he muttered, with a jerky little nod of satisfaction, and turned
his attention to the blotting-pad. A few minutes' close inspection and
he drew the top sheet away and, rolling it up, placed it in the
breast-pocket of his overcoat. Again he closed the desk and glanced at
his watch. A touch at the bell summoned the footman.

"I don't think I'll wait, after all," said Foyle. "Time's getting on,
and I've several things to attend to."

"Shall I tell Lady Eileen you called, sir?"

In deep thought Heldon Foyle sauntered away from the house, and Maxwell

Once he took out a pencil and drafted a description of Grell's
appearance and dress as Roberts had seen him. As a matter of course, he
intended that to be telegraphed and telephoned to his men all over
London. It was as well not to neglect any precaution.

He was passing through the little back door which leads to the quarters
of the C.I.D. when he came face to face with a young man bearing all the
appearance of a clerk who was just passing out. "Hello, Phillips!" he
exclaimed. "You've been after Lady Eileen, haven't you? What luck did
you have?"

"I've just reported to Mr. Green, sir," was the answer. "She walked to
the Metropolitan and Provincial Bank and took a taxi when she came out.
I followed in another cab, but my man punctured a tyre in the Strand and
I missed her."

Foyle frowned and gripped t
