Ricky is a street kid – sharp, quick and usually up to no good.

When he tries to steal from the wrong people, he is saved by a mysterious man called Felix who makes Ricky a compelling offer: a flat and a hundred pounds a week.

All he has to do is take lessons from Felix. Soon Ricky finds himself learning about surveillance techniques, how to make himself invisible in a crowd and hand to hand combat.

But what is this all for? Ricky has no idea until he’s given his first mission and finds his whole world turned upside down.
