Angel on the Inside written by Mike Ripley performed by Dave John on Audio CD (Unabridged)

So why is Angel trying to break into a prison? The trouble starts when Angel's wife Amy's ex-husband is re-arrested, having been released from prison only a month before. And some very seedy characters start taking a close interest in what the ex-husband was doing in between his release from prison and subsequent re-arrest for stalking Amy - but Amy's not talking. So it's up to Angel to find out why his wife is being so...

reticent and why another mystery person is so fascinated by the ex's movements - and the only way to do that is to discover what was going on in prison prior to his release.

So Angel has to figure out how to break in; he doesn't know yet how he'll do it, only that it's going to be just like The Great Escape - only in reverse...
