Death of a Dude (A Nero Wolfe Mystery)
The mountain couldn't come to Wolfe, so the great detective came  to the mountain--to Lame Horse, Montana, to be exact. Here a city  slicker got a country girl pregnant and then took a bullet in the back.  Wolfe's job was to get an innocent man exonerated of the crime and  catch a killer in the process. But when he packed his silk pajamas and  headed west, he found himself embroiled in a case rife with local  cynicism, slipshod police work, and unpleasant political ramifications.  In fact, Nero Wolfe was buffaloed until the real killer struck again,  underestimating the dandified dude with an unerring instinct for  detection.
