t to the official outlook of my
companion, and the official outlook is always peculiar, it might have
seemed otherwise.

"The clever and cunning villain who planned this thing," I said, "has
overstepped himself, as you say, Gatton. If the murder was planned
artistically, in his attempt to throw the onus of the crime upon
innocent shoulders he has been guilty of a piece of very mediocre
work. It would not deceive a child."

"No, I agree with you there. The discovery of that photograph has done
more to convince me of the innocence of Miss Merlin than any amount of
testimonials to her good character could ever have done. You see," he
added, smiling whimsically, "all sorts of people hitherto unsuspected
by their closest friends of criminal tendency, develop that taint, so
that I am never surprised to find a convicted thief or assassin
possessed of credentials which would do justice to an Archbishop. But
when I see an obviously artificial clew I recognize it a mile off.
Real clews never stare you in the face like that."

Coming out of the front door, we walked down the leaf-strewn drive to
find that the constable on duty at the gate had been joined by a
plain-clothes man who was evidently waiting to speak to the Inspector.

"Yes?" said Gatton eagerly, at sight of the newcomer.

"We have her, sir," he reported tersely.

"Does he refer to Marie?" I asked.

Gatton nodded.

"I think, Mr. Addison," he said, "I will proceed immediately to Bow

with me or are you otherwise engaged?"

I hesitated ere I replied:

"I do not particularly want to confront this woman, but I should be
much indebted if you could let me know the result of your
examination."

"I shall do that without fail," said Gatton, "and some time to-day I
should be obliged if you could provide me with the facts concerning
the little cat-images which you said you had in your possession."

"Certainly," I agreed. "You are still of the opinion that the mark
upon the crate and the image of the cat-woman have an important
bearing upon the crime?"

"I don't doubt it," was the reply. "If the photograph clew is a false
one, the cat clew is a true one and one to be followed up. Perhaps,"
he added, "it would be as well if you returned now and looked out the
points which you think would be of interest, as when I come I may not
have long to stay."

"I will do so," I said, "although I think I can lay
