A conjoined twin’s disappearance leads a London journalist to a mystery reaching back to the turn of the last century in this “hefty suspense thriller” (Publishers Weekly, starred review).

Journalist Harry Fitzglen is intrigued by his latest subject, the London artist Simone Anderson, whose enigmatic photographs hint at a mysterious past. What exactly happened to Simone’s twin sister Sonia, to whom she had once been conjoined—and who disappeared years before? And how might Simone and Sonia be connected to another pair of conjoined twins, Viola and Sorrel, born nearly a century ago?

Every question Harry asks points him to the Shropshire village of West Fferna and a ruined mansion on the Welsh border called Mortmain House. As Harry uncovers the grim history of Mortmain, he finds himself drawn into a set of interlocking mysteries, each one more curious and disturbing than the last.

Set in three different time periods across the twentieth century, A Dark Dividing is “reminiscent of Henry James or Wilkie Collins … riveting and hard to put down” (Portland Book Review).
