“That’s why I sent the girls off to Sir James.  I was sure they’d fetch up at the house in Soho sooner or later.  I threatened Julius with the revolver, because I wanted Tuppence to repeat that to Sir James, so that he wouldn’t worry about us.  The moment the girls were out of sight I told Julius to drive like hell for London, and as we went along I told him the whole story.  We got to the Soho house in plenty of time and met Mr. Carter outside.  After arranging things with him we went in and hid behind the curtain in the recess.  The policemen had orders to say, if they were asked, that no one had gone into the house.  That’s all.”

And Tommy came to an abrupt halt.

There was silence for a moment.

“By the way,” said Julius suddenly, “you’re all wrong about that photograph of Jane.  It was taken from me, but I found it again.”

“Where?” cried Tuppence.

“In that little safe on the wall in Mrs. Vandemeyer’s bedroom.”

“I knew you found something,” said Tuppence reproachfully.  “To tell you the truth, that’s what started me off suspecting you.  Why didn’t you say?”

“I guess I was a mite suspicious too.  It had been got away from me once, and I determined I wouldn’t let on I’d got it until a photographer had made a dozen copies of it!”

In the pause that ensued, Mr. Carter took from his pocket a small shabby brown book.

He opened the book, and turned the thin pages.

“. . .  It is madness to keep this book.  I know that.  It is documentary evidence against me.  But I have never shrunk from taking risks.  And I feel an urgent need for self-expression....  The book will only be taken from my dead body....

“. . .  From an early age I realized that I had exceptional abilities.  Only a fool underestimates his capabilities.  My brain power was greatly above the average.  I know that I was born to succeed.  My appearance was the only thing against me.  I was quiet and insignificant—­utterly nondescript....
