d squarely in the eyes,
said:

"This is the organization that you're going to beak up!"

Desmond raised his eyebrows.

"Who is at the head of it?" he asked quietly.

The Chief, smiled a little bitterly.

"By George!" he cried, slapping his thigh, "you've rung the bell
in one. Okewood, I'm not a rich man, but I would gladly give a
year's pay to be able to answer that question. To be perfectly
frank with you, I don't know who is at the back of this crowd,
but..." his mouth set in a grim line, "I'm going to know!"

He added whimsically:

"What's more, you're going to find out for me!"

Desmond smiled at the note of assurance in his voice.

"I suppose you've got something to go on?" he asked. "There's
Nur-el-Din, for instance. What about her?"

"That young person," replied the Chief, "is to be your particular

at any rate, in the thick of it. It will be part of your job to
ascertain the exact role she is playing."

"But what is there against her?" queried Desmond.

"What is there against her? The bad company she keeps is against

manager, a fat Italian who calls himself Lazarro, did you notice

alias Le Tardenois is a very notorious international spy who
after working in the Italian Secret Service in the pay of the
Germans was unmasked and kicked out of Italy... that was before
the war? This pleasant gentleman subsequently did five years in
the French penal settlements in New Caledonia for robbery with
violence at Aix-les-Bains... oh, we know a whole lot about him!
And this woman's other friends! Do you know, for instance, where
she often spends the week-end? At the country-place of one Bryan
Mowbury, whose name used to be Bernhard Marburg, a very old hand
indeed in the German Secret Service. She has identified herself
right and left with the German espionage service in this country.
One day she lunches with a woman spy, whose lover was caught and
shot by the French. Then she goes out motoring with..."

"But why in Heaven's name are all these people allowed to run
loose?" broke in Desmond. "Do you mean to say you can't arrest
them?"

"Arrest 'em? Arrest 'em? Of course, we can arrest 'em
