Naked Crow 11: Jinn

Lizzy, an almost forgotten friend of Sheila and Jeremy, gets in touch with a cry for help.
She, with her group of friends, managed to summon a Jinn and now they're in a fix. The Jinn doesn't want to go home and causes problems. Sheila's reputation speaks for itself, and so she is Lizzy's last resort.
We also encounter a dangerous man at the Mighty Oaks. He's not dangerous to others, though, but to himself.
As usual, there's a lot going on and there are many questions to be answered. And not only by that Jinn.
