A murder staged to look like a suicide fools everyone except Albert Smith. He knows better. In Lyme Regis with his faithful dog, the victim invited him to visit the seaside resort. Now he's dead and Albert wants to know why.

But when the trail of clues leads Albert into a darkened courtyard, Rex finds himself left to investigate alone and all too soon a second body is discovered. Is there a killer out there? Or are the suicides just poorly timed?

In a deadly race to the finish, Albert knows he may have to sacrifice himself to save the next victim and Rex must risk everything to save Albert.

In a battle high on the cliffs above the Jurassic Coast, does that leave anyone to save Rex?

One final roll of the dice, that's all Albert and Rex wanted. Maybe they ought to have gone straight home.
