A porter was called up after a tenant had noticed water fell down from ceiling: the apartment upstairs had a water drop. When they got in, they're shocked in finding a woman stabbed to death lying on the ground. Detectives soon realized she's a prostitute due to the high amount of cash hidden under the mattress and for some sex toys located in bedside cabinet. Brooks and Devlin started questioning some johns (even a eighteen years old nerd) as well as the secretive porter, who used to have arguments over the victim. A fellow Serbian hooker (Maya Lubinsky) told them her friend had an affair with a renowned history professor and writer (he wrote bestsellers related to crusades); not a proper relationship for her, but he was really in love, giving her luxurious gifts. The problem is that he's married with a sick son, but the wife doesn't seem to care about the affair, she wants to save her marriage. Is it possible? Be ready for the twist ending.
The episode is not so original (a man who cheat on his wife) but still enjoyable. How can a family man fall in love with a prostitute much younger than him? You have to be crazy.
