"I wonder at that, considering how we talked them over," said
Ackworth, sitting down again, and slipping his arm round her as though
to protect her from harm. "Don't you remember, darling, that one
person after another was found murdered in houses and in streets, with
a purple fern stamped on the forehead. And in every case, a warning of
a stamped fern was sent beforehand. Then the police caught one man
red-handed. He was tried and hanged, but he would not give away his
associates. But the police gathered that he was one of a gang who
killed people to get money--since all the victims were wealthy--and in
every instance the sign of the association, a purple fern, was stamped
on the forehead of the victim. But with the hanging of the man that
was caught, the murders ceased. This is the first time I have heard of
a new warning being given. I should recommend Mr. Horran to take care
of himself."
"Oh, Anthony, how terrible. Do you really think that he is in danger
of his life?"
"Judging by the fact that seven people, men and women, were killed,
after such a warning had been sent, I do think it is dangerous. I
shall see the local police about this at once. The house must be
watched. I wonder why Horran is to be killed. Is he very rich?"
Recollecting what Clarke had said, Clarice could reply easily: "On the
contrary, he has nothing but what he earns by acting as our guardian.
I wish he could explain exactly how he picked up the letter; but he is
still asleep."
At this minute the wheels of a carriage were heard. Clarice, wondering
if the new arrival was Jerce, opened the French window and stepped out
on to the terrace, now sloppy with mixed snow and water and mud. She
strolled to the end, followed by Anthony, and saw that Dr. Jerce had
indeed arrived. He was stepping out of a hired fly, and had just
handed the man his fare, when he caught sight of Clarice. At once he
came towards her with outstretched hand. She took it unwillingly
enough. "I received a wire from Wentworth," he said, anxiously. "I
hope my old friend is not very ill again."
"No. He's in a sound sleep, and Dr. Wentworth is puzzled over the
length of his slumber. Come in this way." And she went along the
terrace.
"Thank you. Ah, Mr. Ackworth, how are you? Quite a change in the
weather, isn't it? And I--why, what's the matter?"
The ejaculation was caused by a cry from Clarice. She had picked up a
small object, which the thaw had revealed. It was a small gold box,
and on its face was set a curved fern in amethysts.
"The Purple Fern again!" exclaimed Ackworth, amazed.
