A naked man plunges to his death in a fruit stand. However, investigation determines he wasn't forced out the window. He had actually been poisoned a few hours earlier. He turns out to be a serial seducer, who mysteriously deviated from his usual MO to pick up higher class, and even married, women. While Ryan is doing a liquid cleansing diet with Jenny before their wedding, Castle comes up with alternative, business-related motives and suspects in addition to the many scorned women.

When Lainie mentions that the victim had been poisoned with colchicine, Castle mentions that it is a drug used to treat rheumatism. The most common condition treated with colchicine is gout, not rheumatism. Colchicine is also used in plant breeding; treatment of seedlings with a colchicine solution doubles the chromosomes and enhances various characteristics of the plant; however, the treated plants are poisonous; only the succeeding generations are safe for consumption. An episode of Quincy M.E. featured a plot centered around stolen marijuana plants that had been treated with colchicine to increase their potency, becoming lethal to anyone who smoked them.
