The Bloodied Ivy

Description for THE BLOODIED IVY by Robert Goldsborough:

He was a man a lot of people hated, even in death. He was Hale Markham, a professor at an upstate New York College, a man infamous for his poisonous jealousy, backstabbing, and character assassination. His death is graded accidental. As Archie pokes about the ivy, Nero Wolfe is ensconced within his brownstone, professing no interest in the case...until Archie lands in jail. Now the enraged great detective must do the unheard of: he must haul his legendary girth from his favorite armchair and storm into the wilds of the outer world to snare a murderer magna cum laude.

This is #3 in A Nero Wolfe Mystery.
