The Back Road Mystery

He stomped hard onto the brake pedal, but there was no stopping. As his vehicle pitched and tumbled into the darkness, a glimpse in his rear-view mirror revealed a face; caught in the flash of his taillight. With both hands clutched tightly to the steering wheel, Bob and his truck plunged down the steep embankment into the darkness. The truck finally came to an abrupt rest at the bottom of the crevasse.
The engine died while one headlight continued to shine into the darkness. All was quiet and Bob found himself trapped, dying beneath the bent steering wheel. A mystery unfolds, and two young men attempt to solve it.
