"Come here," she cried, "I have a rig."
They found her seated in a buggy. Both climbed in beside her. Keith took the reins, and lashed the horse with the light whip. The astonished animal leaped; the buggy jerked forward.
Then began a wild, careering, bumpy ride into the night. The road was fearful and all but invisible. The carriage swayed and swung dangerously. Keith drove, every faculty concentrated. No one spoke. The dim and ghostly half-guessed forms of things at night streamed past.
"Who sent that letter?" demanded Keith finally.
"Mex wouldn't tell me," replied Krafft.
"How long ago did he deliver it?"
"About an hour."
The horse plunged frantically under the lash as this reply reached Keith. The buggy was all but overturned. He pulled the frantic animal down to a slower pace, and with an obvious effort regained control of himself.
"Can't afford an accident!" he warned himself.
"Are you armed?" Mrs. Sherwood asked him suddenly.
