The locked room
(Book)

"Originally published as The Locked Room in Great Britain in 2022 by Quercus."--Title page verso.

Ruth is trying to conduct anthropology classes online from her living room while struggling to home-school her daughter, Kate, now a restless and inquisitive 11 year-old. Then Inspector Harry Nelson, her on-and-off-again lover, involves her in a series of murder/suicides. Ruth has also been working on a mystery of her own. While clearing out her late mother's effects, she finds a photo of her (Ruth's) cottage with the annotation, "Dawn 1963." This is the same mother who abhorred Ruth's home. Meanwhile, her Druid friend Cathbad contracts the virus and is fighting for his life, and Ruth places herself in great danger by venturing out to deal with a situation involving the unearthing of a medieval plague victim and rumors of a ghost called The Grey Lady of Tombland.
