Erle Stanley Gardner 
Bats Fly at Dusk 

A cool girl hunt is what the blind man wanted. He was searching for a pretty young woman, soft spoken and slender, whom he’d never seen but knew had vanished, and he was willing to pay Bertha Cool anything to find her. The whole thing seemed impossible and sounded suspicious, but the man’s money was right – even if his motives weren’t – and given the choice Bertha always followed the dollar sign. Only this time, the dollar sign pointed to murder and fingered Bertha Cool as a red hot suspect.
