An abandoned motor cruiser is found stranded on South Binness Island in Langstone harbour.

There's a large pool of blood on the deck and heavy crimson spatter up the side of the storage lockers. But no sign of a body on board.

Detective Inspector Andy Horton is on the case. He discovers the boat owner's identity: Neil Spender, a Portsmouth binman. But he's nowhere to be found.

It's not long before Horton's pulled into another investigation involving an unusual robbery at a local art gallery. Three paintings have been switched for forgeries.

The gallery owner is adamant the originals have been stolen. But there's no evidence of a break-in.

Now Horton and Cantelli have a murder investigation to solve and a cunning art fraudster to find. Time is ticking for our dogged detectives . . .
