The Perfect Girl by Andy Maslen

How do you stop a killer no one believes exists?DS Kat Ballantyne wants to know why a perfect girl like Rosie Duggan would jump to her death from a multistorey car park. Everyone is saying she took her own life. But Kat is unconvinced. Girls like Rosie-bright, popular, well adjusted, and with her whole life ahead of her-don't fall from tall buildings. Unless someone pushes them. When a second student dies the same way, Kat is the only one asking the hard questions. As she digs deeper, a disturbing pattern begins to emerge. With loyalties fracturing and powerful enemies circling, shocking DNA evidence leads to a surprising suspect. But has Kat really found the killer? Or has she just been played?
