"The Upham Road," said Tennant, feeling nothing at all.
Cass got the car under way and Tennant sensed them coming through. They warned him that his chauffeur was carrying a weapon concealed in an inside pocket.
As if I didn't know! Tennant snapped back at them.
Cass tried to drive him past the spot beyond the bridge where the gateway lay hidden in its armor of invisibility. He evidently planned to go miles from the house before doing whatever he had decided to do.
Tennant thought he knew. It would involve riding the back roads like this one for fifteen or twenty miles, perhaps farther. He suspected that the quarry pond in South Upham was his intended destination. There would be plenty of loose rock handy with which to weigh down his body before dumping it into the water.
If it were recovered, Cass and Agatha could alibi one another. In view of his earlier disappearance, this would be simple. Of course there was the maid, but Cass had enough money and smooth talk to manage that angle. They could undoubtedly get away with killing him.
"Stop," said Tennant, just across the bridge.
"What for?" Cass countered and Tennant knew it was time to act. He wrenched the key from the ignition switch, tossed it out of the car. Cass braked, demanded, "What in hell did you do that for?"
"I get out here," Tennant said. "You didn't stop."
