Colin Bannock is hiding quite the secret.

By day, he's a smooth-talking lawyer. After hours, he is someone else entirely.

He corners Arnold Landon, wanting him to join his society of history fanatics.

Appalled, Arnold declines outright. He's never been a joiner and, besides, he has enough on his plate already.

He is hunting for a lost and ancient treasure. And he knows the hiding place is close.

Then Bannock's body washes up on the banks of the River Tyne, battered and bloated beyond recognition.

Was he also chasing the mythic treasure?

The race is on to claim the hoard. And someone out there will stop at nothing to get there first.
