"Because you let her in!"

Thalassa surveyed him with the shadow of a smile on his motionless face.
"Do you take me for a fool?" he said. "I let nobody in."

"Thalassa," said the detective earnestly, "let me advise you, for your own
sake, to tell the truth now. You may be keeping silence through some
mistaken idea of loyalty to your master's daughter, but that will do her
no good, nor you either. I know more than you think. If you persist in
keeping silent you will put yourself in an awkward position, and it may be
the worse for you. You were seen listening at the door of the room
downstairs on the day of your master's death."

"So that's it, is it? You think you'll fit a rope round my neck? I'm to
say what you want to save it? To hell with you and your policeman's
tricks! I don't care that for them." He snapped his long brown fingers in
Barrant's face.

"You've a bold tongue, you scoundrel," said Barrant, flushing angrily.
"Take care where it leads you. Once more, will you tell me the truth?"

"I've told you all I know."

"Do you mean to tell me that you did not see your master's daughter, or
let her into the house?"

"I did not."

"Could anybody have got into the house without your knowledge?"

"Maybe."

"Did you hear anybody?"

The open sneer on Thalassa's face suggested that he was not to be caught
by verbal traps. Barrant perceived, with a smouldering anger, that the man
was too clever to be tricked, and too stout of heart to be frightened. By
accident or design he had a ready story which was difficult to demolish
without further knowledge of the events of that night. Barrant decided
that it would be useless, at that moment, to apply himself to the effort
of worming anything out of Thalassa. He had shown his own hand too freely,
and placed him on his guard. There was also the bare possibility that he
had told the truth, so far as he knew it. One last shot he essayed.

"You are acting very foolishly, but I shall not arrest you--yet," he said
impressively. "I shall tell the local police to keep an eye on you."

"Is it the Cornish savage from the churchtown--him with the straw helmit?"
said Thalassa, with a harsh laugh.

The last shot had missed fire badly. The lawless spirit of the man was not
to be intimidated by a threat of arrest--a threat which the detective had
reason for not putting into effect just then. Barrant moved towards
