No. 23 has a secret. In this bedsit-riddled south London wreck, lorded over by a lecherous landlord, something waits to be discovered. Yet all six residents have something to hide.
Collette and Cher are on the run; Thomas is a reluctant loner; while a gorgeous Iranian asylum seeker and a 'quiet man' nobody sees try to stay hidden. And watching over them all is Vesta - or so she thinks.
In the dead of night, a terrible accident pushes the neighbours into an uneasy alliance. But one of them is a killer, expertly hiding their pastime, all the while closing in on their next victim...
As a cloying heatwave suffocates the city, events build to an electrifying climax in this dark, original and irresistibly compelling thriller.
