Lisa thinks she has it all-dream job, besotted boyfriend, loyal friends, even her pub quiz team might win. But she’s about to find out that things aren’t quite as they seem. Charismatic Judith, devastated when she lost partner, Martin, in the floods, has moved to Manchester to escape the past. Trawling the Internet by day, haunted by her memories at night, she occupies her time stalking the new friends she met at the Sun pub quiz. Lisa is initially beguiled by the glamorous older woman but soon becomes suspicious of Judith’s motives. As she pits her wits against Judith’s wiles her amateur investigations trigger a murderous chain of events. Who is Judith? And just who is deluded?
