Fluke (1977)
Fluke by James Herbert

A likely tail.

He was a stringy mongrel, wandering the streets of the city, driven by a ravenous hunger and hunting a quarry he could not define.

But he was something more.

Somewhere in the depths of his consiousness was memory clawing its way to the surface, tormenting him, refusing to let him rest. The memory of what he once had been. A man!

James Herbert “One of the world’s most successful horror writers, James Herbert remains one of the least affected and most approachable.”
