The Mystery of Four

Murder is easy … when it doesn’t look like murder.

Tess Morgan has finally made her dream of restoring beautiful Kilfenora House and Gardens into a reality. But the week before the grand opening, her dream turns into a nightmare when a devastating accident looks set to ruin her carefully laid plans. There are rumours that Kilfenora House is cursed, but this feels personal, and increasingly terrifying, as people begin to die in a pattern that mirrors past events.

Could Tess herself be in danger? Clarissa Westmacott, ex star of stage and screen, certainly believes so, particularly when she discovers that someone has been picking purple-flowered aconite in the Poison Garden. And Clarissa will stop at nothing to save the friend she has come to see as a daughter…
