Is it safe to breathe?
London June 1910.
Fighting her corner in a man’s world, Dr Margaret Demeray works as a pathologist in a London hospital for the poor. Suppressing her worry that she’s breaching confidentiality, Margaret gives a stranger called Fox information about a dead down-and-out, in the hope he’ll use it to raise awareness of bad working conditions. But when a second man appears to die the same way, Margaret starts to wonder why the enigmatic Fox keeps turning up to ask ever more complex questions. She decides to work alone, uncertain of his motives and wary of her attraction to him. Once she starts investigating however, her home is burgled, she’s attacked in broad daylight and a close friend becomes distant. Fox offers the chance to forge an alliance, saying he knows why the men have died but needs her to find out what is killing them and who is behind it. Yet how come the closer she gets to him the more danger she faces? And how can a memory she’d buried possibly be linked to the deaths? Margaret must discover the truth before someone – known or unknown – silences her for good.
