It's the height of summer in Australia, 1979, and on a quiet suburban cul-de-sac in Canberra a housewife is scrubbing the yellow and white chequered tiles of the bathroom floor. But all is not as it seems. For one thing, it's 3 am. For another, she is trying desperately to remove all traces of blood before they stain. Her husband seems remarkably calm, considering he has just murdered their neighbour. As the sun rises on Warrah Place, news of Antonio Marietti's death spreads like wildfire. Gossip is exchanged in whispers and suspicion mounts. Twelve-year-old Tammy launches her own investigation, determined to find out what happened, but she is not the only one whose well-meaning efforts uncover more mysteries than they solve.
