Rick Castle once joked about writing murder mysteries because he came across a dead body. In Castle Season 7 Episode 23 he reveals that the joke wasn't very far from the truth. 

Turns out an 11-year old Rick stumbled upon a dead woman in "Hollander's Woods" and a masked killer who threatened him if he ever told a soul.

Despite calling the police, the woman's body was never found and Castle began to think the event never actually took place. That was until a current body and a creepy figure in a mask directly matched his memories.
