Lee describes Miss Flynn's suicide by drowning - he later refers to a spate of suicides wherein even the coroner killed himself.
Lee also recounts the tale of the hangman who unknowingly hanged his son, then went home and hanged himself once he discovered what he'd done.
Mentioned a few times while referring to crimes which took place in Slad.
Laurie's friends unsuccessfully conspire to rape a girl called Lizzy Berkeley in Brith Wood - this goes no further than Bill Shepherd putting a hand on her shoulder and being smacked with a bag of crayons - Lee then mentioned that Bill was raped himself soon afterward.
Lee's Uncle Sid is said to repeatedly attempt suicide after his bus company suspends or fires him - though this is to avoid his wife Alice's anger and turn it into anxiety over his fate rather than any true suicidal feelings.
It's purposefully left very vague - Laurie doesn't describe in much detail what he and Rosie drunkenly got up to under the hay wagon other than kissing once. It's very possible and implied that they could have had sex.
