Tulley Gross, a no nonsense twenty-five year veteran of the force and his partner of ten years, Pete Prusak.
Tulley is a rotund look alike for Alfred Hitchcock and his partner Pete who has a liking for Sherlock Holmes and Agatha Christie whose methods he's constantly bringing into the case to the chagrin of his partner.
One murder, two murders, three... the two homicide cops have a serial killer on their hands when a yellow rose shows up on each body. When a red roses then a white ones begin to appear as the body count rises, the two homicide cops have three serial killers at once working the precinct. the mess gets worse when the three begin sending notes to the station complaining about a forth one, this one a woman! It's hard enough to solve one case now they have four! with an ending worthy of Sherlock Holmes, the two work the city, the killers, and the clock as time is quickly running out on them...
