Deadlock by Simon Fox

Archie Blake thought his policeman father teaching him how to pick locks and open safes was just a bit of fun. But when a diamond necklace is stolen and his dad is arrested, Archie realises the only way to prove Dad's innocence is to go on the run and use everything he's learned to uncover the truth.

But Archie soon finds himself deeply tangled in the criminal underworld, where it's hard to know who to trust and even harder to see what's right or wrong. Will Archie be able to find a way out before it's too late?

I loved this one! I had really enjoyed Running Out of Time last year and this story was just as good! Pacey adventure with characters you are rooting for complicated but lovely friendships and family relationships.
