The Dog Sitter Detective Takes the Lead

Dog sitter Gwinny Tuffel is staying on an ageing rock singer's houseboat in London's Little Venice looking after his border collie while he goes on tour. But during the annual Canal Carnival the singer's body is discovered having never made it out of London. The police dismiss it as an accident but Gwinny suspects murder most foul. It is up to her to solve this curious crime.
