Detective Nick Chasm is obsessed with his profession, even outside his Chicago city jurisdiction. Bringing down bad guys ranks second only to his love for his 82—year-old mother.

When she insists he come home to Eden Gorge to investigate the vehicular homicide of her male companion, he's prepared to ride up on his Harley and bring her comfort despite hellish memories of his police officer father.

Soon after arrival, Nick learns there was a related suicide the same night.

It won't be a day trip after all.
