Death in Shetland waters - 6 (First edition.)

Cass Lynch has achieved the post of third officer aboard her beloved Norwegian sail-training ship, Sorlandet.

They're sailing from Norway to Ireland as part of the Tall Ship's race.

An unnerving early-morning encounter leads to suspicions that there's a stowaway on board - yet a police search finds nobody.

Then one of the trainees goes missing - Cass and her lover DI Gavin Macrae find themselves up against a ruthless killer.

Cass also needs to confront her personal dilemma - if she wants a settled life with Gavin, she'll have to leave the sea, but could she bear to do that?
