That night, with Christine's agreement, Marcia and Rusty (Who was driving) waited outside the Atwell estate. They brought along a camcorder (which Christine agreed with on condition that the recordings were given to her) and a few other things.
Just before dusk, a small gang of street punks turned up and threw a stone at the wall next to an upstairs window. Then Tommy exited the house and went off with them.
"Let's follow at a distance" said Marcia.
Marcia and Rusty followed the youths to a nearby alley. Getting out of the car and peering round the corner, they saw Tommy and the other youths remove their shoes and jackets.
The two investigators were unprepared for what came next. The youths in the alley all started growing hairier and bulkier, faces growing muzzles, hands and feet becoming paws. Tommy and the gang were turning into werewolves!
"Are you getting all this, Rusty?" asked Marcia
"It's zoomed in and all." replied Rusty, holding the camera round the corner "How do we tell Christine her son's a werewolf though?"
