Doc Candle nodded. Collins knew then that Michaels really would shoot him in the head if he said anything more, so he kept quiet.
Candle held the door. They managed to get the stretcher down the back steps, and right into the black panel truck. They fitted the stretcher into the special sockets for it, and Doc Candle closed the double doors and slapped his dry palm down on the sealing crevice.
