The bonus about being laid low by illness has definitely been the excellent books to read - this was one of them.
From the Blurb:
When eighteen-year-old Chloe Emery returns to her West London home she finds her mother missing, the house covered in blood. Everything points to murder, except for one thing: there’s no sign of the body.
London detective Maeve Kerrigan and the homicide team turn their attention to the neighbours. The ultra-religious Norrises are acting suspiciously; their teenage daughter and Chloe Emery definitely have something to hide. Then there’s William Turner, once accused of stabbing a schoolmate and the neighborhood’s favorite criminal. Is he merely a scapegoat, or is there more behind the charismatic façade?
As a body fails to materialize, Maeve must piece together a patchwork of testimonies and accusations. Who is lying, and who is not? And soon Maeve starts to realize that not only will the answer lead to Kate Emery, but more lives may hang in the balance.
