which he very carefully let fall in the tub.

"I wish it was light so that we could see it," Curtis whispered in
Kelson's ear. "I believe Jews have different coloured blood to other
people."

Though Kelson was apprehensive, Hamar did not appear to have heard;
his whole attention was riveted on the mirror, on the face of which
was a reflection of the moon.

"I knew nothing would happen," Curtis cried, "you had better wipe your
knife or you'll be arrested for severing some one's jugular. Hulloa!
what's up with the cat?"

Hamar was about to tell him to be quiet when Kelson caught his arm.
"Look, Leon! Look! What's the brute doing? Is it mad?" Kelson gasped.

Hamar turned his head--and there crouching on the floor, in the
moonlight, was the cat, its hair bristling on end and its green eyes
ablaze with an expression which held all three men speechless. When
they were at last able to avert their eyes a fresh surprise awaited

was right enough. Besides, why are your teeth chattering?"

"Why are yours?" Curtis retorted; "why are Matt's?"

"Shall we try the second?" Hamar asked.

"No!" Kelson and Curtis said in chorus. "No! We've had enough for one
night. We'll be off!"

"I think I'll come with you," Hamar said, "after what has happened I
don't quite relish sleeping here alone--or rather with that cat.
Hi--Satan, where are you?"

Satan was not visible. It had probably hidden under the bed, but as no
one cared to look, its whereabouts remained undiscovered.

With the coming of the sun, the terrors of the night wore off, and the
trio separated. Hamar would on no account accept his friends'
invitation to breakfast on the sausages and ham they had run such
risks in procuring; he made ha
