I had a tip-off about this from a friend at reading group. The CWA International Dagger Award winning, The Darkest Room by Johan Theorin is being serialised on Radio 4 Extra. The first of five thirty-minute parts begins on Saturday at 23.30.
If you can't stay up then I imagine it will be on iPlayer very shortly afterwards!
