the unfortunate man, discovered that Jackson was no other than the
wanted man in the Millinborn murder, a crime which most of our
readers will recall.

"Dr. van Heerden stated to our representative that the man had
represented that he was a friend of the late John Millinborn, but
was anxious to get to Canada. He had produced excellent
credentials, and Dr. van Heerden, in a spirit of generosity,
offered to assist him. At the eleventh hour, however, he was struck
with the likeness the man bore to the published description of the
missing man in the Millinborn case, and was on the point of
telegraphing to the authorities at Liverpool, when he discovered
that Jackson had missed the train.

"The present tragedy points to suicide. The man, it will be

examination reveals the presence in the body of a considerable
quantity of cyanide of potassium, and the police theory is that
this was self-administered before the collapse. In the man's pocket
was discovered a number of cyanide tablets.

"'I am satisfied,' said Dr. van Heerden, 'that the man already

of cyanide--one of the deadliest and quickest of poisons--suggests
that he had the project in his mind. I did not see his action or,
of course, I should have stopped him!'"

Oliva Cresswell read this account in her room two nights following the
tragedy and was struck by certain curious inaccuracies, if all that the
doctor had told her was true.

Mr. Beale read the account, smiled across the table grimly to the
bearded superintendent of the Criminal Investigation Department.

"How does that strike you for ingenuity?" he said, pushing the paper
over the table.

"I have read it," said the other laconically, "I think we have
sufficient evidence to arrest van Heerden. The tile from the Grand
Alliance shows traces of digitalis."

Beale shook his head.

"The case would fall," he said. "What evidence have you? We did not
confiscate his medicine-case. He might have dropped a tablet of
digitalis by accident. The only evidence you could convict van Heerden
on is proof that he brought with him cyan
