His partner, Felix (“Dude”) Durand, will never forget the homicide case Till solved in record time relying in large part on his sensitive nose. Closing the case leaves the partners to consult their personal beliefs in justice: did they make the city a safer place taking down the perpetrator, or did the murderer do so when she took down the victim?
