crime, its motive, or its possible author?"

"God forgive me if I do any man an injury, but in these last few days I
have had my suspicions," she exclaimed.

"Tell me your reasons."

"It arose out of a chance remark by Nellie. She was discussing with me her
inexplicable antipathy to Mr. Capella, even during the time when they were
outwardly good friends. She said that once he showed her a Japanese sword,
a most wonderful piece of workmanship, with veins of silver and gold let
into the handle and part of the blade. To the upper part of the scabbard
was attached a knife--a small dagger--similar--"

"Yes, I understand. An implement like that used to kill Sir Alan
Hume-Frazer."

"Exactly. Nellie at first hardly realised its significance. Then she
hastily told Capella to take it away, but not before she noticed that he
seemed to understand the dreadful thing. It is fastened in its sheath by a
hidden spring, and he knew exactly how to open it. Any person not
accustomed to such weapons would endeavour to pull it out by main force."

Brett did not press Mrs. Eastham to pursue her theory. It was plain that
she regarded the Italian as a man who might conceivably be the murderer of
his wife's brother. This was enough for feminine logic.

Hume, too, shared the same belief, and had not scrupled to express it
openly.
