is throat and his at mine. O'Connor with a jiu-jitsu movement bent
Farrington's other arm until he released me with a cry of pain.

In front of me I saw Craig grasping Mrs. Popper's wrists as in a vise.
She was glaring at him like a tigress.

"Do you suppose for a moment that that toy is going to convince the
world that Henry Vandam has been deceived and that the spirit which
visited him was a fraud? Is that why you have lured me here under false
pretences, to play on my feelings, to insult me, to take advantage of a
lone, defenceless woman, surrounded by hostile men? Shame on you," she
added contemptuously. "You call yourself a gentleman, but I call you a
coward."

Kennedy, always calm and collected, ignored the tirade. His voice was
as cold as steel as he said: "It would do little good, Mrs. Popper, to

this additional proof of your guilt by trying to destroy the evidence.

are an astute criminal, Mrs. Popper, but to-night you are under arrest
for the murder of Mary Vandam and the attempted murder of Henry Vandam."

VI. The Diamond Maker

"I've called, Professor Kennedy, to see if we can retain you in a case
which I am sure will tax even your resources. Heaven knows it has taxed
ours."
