In a few seconds, Betty lay in the corner of the small room. The glare of Bob’s flashlight revealed its solid stone walls. There was not a crevice in their surface. A sneer came from the man behind the light.
“You can think it over here,” were Bob’s malicious words. “You’ve got an hour or two — at the most.
“You’ve found out plenty tonight. You know who killed Hodgson. Tell it — if you can!”
The flashlight was extinguished, but Betty could see the forms of the men in the lighted passage. A huge, dark wall swung inward. Something clicked as the wall came into place.
Muffled sounds followed. The posts were being hammered back to their positions. Then came silence horrible silence. The men had gone!
Here, in a vault of doom, a tiny room hewn in solid stone, Betty had been left to die. The closing of the barrier had sealed the vault so closely that no draft of air could enter. Impenetrable blackness seemed to engulf the helpless girl.
The choking hands of the hideous-faced Clink would have been merciful compared to the slow, gruesome death that now held Betty Mandell within its frightful grasp!
But the false Bob Galvin and his heartless allies had reckoned without the shadowy figure Betty had seen in the study.
