down the courtyard convinced him that Boko had
disappeared. He jumped into a taxi, gave an address in Belgrave Square,
and within a quarter of an hour was ushered into the presence of Mr.
Spencer Wyatt, who was seated at a writing-table covered with papers.

"Mr. Norgate, isn't it?" the latter remarked briskly. "I had Mr.
Hebblethwaite's note, and I am very pleased to give you five minutes. Sit
down, won't you, and fire away."

"Did Mr. Hebblethwaite give you any idea as to what I wanted?"
Norgate asked.

"Better read his note," the other replied, pushing it across the table
with a little smile.

Norgate took it up and read:--

"My dear Spencer Wyatt,

"A young friend of mine, Francis Norgate, who has been in the Diplomatic
Service for some years and is home just now from Berlin under
circumstances which you may remember, has asked me to give him a line of
introduction to you which will secure him an interview during to-day.
Here is that line. Norgate is a young man for whom I have a great
friendship. I consider him possessed of unusual intelligence and many

am not. This isn't any ordinary visit of mine. I have come to see you on
the most urgent matter which any one could possibly conceive. I have come
to give you the chance to save our country from the worst disaster that
has ever befallen her."

Mr. Spencer Wyatt looked at his visitor steadily. His eyebrows had drawn
a little closer together. He remained silent, however.

"I talk about the things I know of," Norgate continued. "By chance I
have been associated during the last few weeks with the head of the
German spies who infest this country. I have joined his ranks; I have
become a double traitor. I do his work, but every report I hand in is a
false one."

"Do you realise quite what you are saying, Mr. Norgate?"

"Realise it?" Norgate repeated. "My God! Do you think I come here to say
these things to you for dram
