SOLVED. Adult Thriller. Multiple main characters- a delivery driver, shop manager and security guard in a shopping centre are the ones I remember. [s]

May be more. Think it opens with the delivery driver being asked to move out by her friend as she keeps stealing and has a shoplifting habit. Moves in with a dodgy fella who keeps his room and I think basement (?) locked. The security guard is living at home with his mum as she has dementia- she keeps thinking her husband is visiting her. The shop manager (Lynne is springing to mind) is a single mum to a 19 year old daughter- the stories all overlap and the housemate ends up being a dangerous stalker of some sort?
