Rob tracks down everyone who is wearing a tracksuit, has worn a tracksuit, or will wear a tracksuit, but comes up with no leads.
Meanwhile, Sam has done his work on the motorway.
He draws up a huge map that diagrams who owns what in and around Knocknaree.
There's a lot of money tied up in this highway business, so much so that it's not out of bounds to think one of the landowners may have hired a hit man.
Later, Rob tries to remember what happened in the woods.
He remembers watching Sandra have sex with the boy in the Metallica shirt in the clearing, and he also remembers finding a "secret garden" (10.59), though he doesn't think that memory could possibly be real.
On Wednesday, Cassie suggests that the Devlins fed the story of the tracksuit to Jessica to throw the cops off the trail.
Rob calls Rosalind to follow up with her, but she doesn't call back.
Cassie and Rob travel to Knocknaree to interview Peter's and Jamie's parents.
While Cassie talks to Peter's parents, Rob waits in the car.
But for some reason he does decide to go inside to talk to Jamie's mother, Alicia Rowan, though.
Alicia wonders if Jamie would be alive if she hadn't tried to send her to boarding school.
She still keeps her bedroom the way Jamie left it, but Rob can't bear to look at it, so he returns to the car while Cassie checks it out.
Cassie thinks it's weird. She mostly just wants to know what Rob remembers.
He's pretty mean, telling her, "We've been through this. Once more, with feeling: I remember sweet shining f***-all" (10.149).
Tell her how you really feel, Rob.
On the road back to the station, Rob sees a mysterious creature run in front of the car and slams the brakes.
Cassie didn't see it. She doesn't know why Rob stopped.
Back at the station, Sam says he found a journalist who has been covering the roadway thing.
The journalist, Michael Kiely, believes that there's a curse or something in the woods, because the injury and fatality rate there is three times the national average.
He has more concrete information, at least: the names of the men behind the three development companies that have bought up all the land in the woods.
Time for a conference with O'Kelly, who tells them they're scaling back operations.
O'Kelly swears they're not giving up (although Rob thinks they are), it's just that there are other cases that now need more attention.
He allows them to keep two floaters.
That night, they hit the pub, and Rob hits on a girl named Anna, but it doesn't go anywhere with her.
Back at Cassie's flat, they wonder where Katy was killed and how the killer got her to the kill site.
Cassie relays a story about a janitor at school who tried to molest her.
He asked if she wanted marbles, and then tried to unbutton her shirt—she says, "kids don't connect things in the same ways grown-ups do" (10.242).
The chapter ends with some interior thought of Rob insisting that he and Cassie are, and will always be, platonic friends. Something about this insistence raises our doubts…
