Psych101
By Doyle
Not something he'd usually do, go off into an alley with a stranger - a male one! - 'cause, hey, regular hetero guy. But maybe he cheated just a little on that Kinsey test, because he's feeling drunk and open-minded and the other guy's hot in a British, retro kind of way. He's not gay, either (spent the last hour crying into his imported beer over some chick; mother abandonment issues?) but the whole neck-nuzzling thing is pretty nice and... ow. The biting, not so pleasant, and were his teeth always that sharp?
Definite therapy case, Holden thinks, and dies.
