Let me help your memory a little.

Did you have no other visitors--before Mr.and Mrs.Pendleton and Dr.Ravenshaw arrived ?" "Visitors ?" There was scorn now in his straight glance, but nothing more.
"Is this a place where there's likely to be visitors ?" "Not in the ordinary course of events"-- Barrant was still smilingly affable--"but the night your master met his death was not an ordinary night.

Somebody may have come to the house." He paused, again searching for some sign of guilty consciousness in the face revealed in such clear outline near him, but saw none.

Again, Thalassa met him with answering look, but remained mute.
"Thalassa"-- Barrant's voice remained persuasive, but to an ear attuned to shades, there was a note of menace underlying its softness--"you know there was somebody else here that night." "Somebody?
Who ?" "Your master's daughter--Miss Sisily Turold." Barrant brought it out sharply and angrily.
Thalassa turned a cold glance on him.

"If you know that why do you ask me ?" he said.
"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.
