Had that face at the window been an optical delusion, after all?
Dyke Darrel was not superstitious, yet in the present case a queer feeling oppressed him, and an awful misgiving entered his mind.
"I cannot believe that the face at the window was other than that of Elliston's; and yet she called him Hubert. It must be that there is a mistake somewhere, and it seems to me that the mad girl is more apt to be deceived than I."
Once more Dyke Darrel returned to the house.
Sibyl Osborne lay in a dead faint on the floor. The detective began chafing her hands at once, and loosened her corsage.
A morocco case fell to the floor.
It was the one containing the alleged picture of Hubert Vander. Under the circumstances Dyke Darrel believed he was justified in examining it.
He opened the case, and was soon gazing at the face of a handsome man.
Although smoothly shaved, the face of the photograph was that of Harper Elliston!
A horrid suspicion now took possession of the detective's brain.
