David Pepin has loved his wife since the moment they met, and he can't imagine living without her - yet he obsessively contemplates her demise. Soon she's dead, and he's both deeply distraught and the prime suspect. The detectives investigating her death have their own conjugal difficulties. Ward Hastroll's wife is inexplicably, voluntarily bedridden. And Sam Sheppard has for decades been especially sensitive to the intricacies of marital guilt, for the most personal of reasons. When Pepin is linked to a hitman, the case begins to resemble the Escher drawings that inspire the computer games Pepin designs for a living. Mesmerizing, hugely poignant, astonishing in its reach, Mr. Peanut is a police procedural of the soul and a first novel of the highest order.
