Diane O'Toole

Diane O'Toole is the author of Rings of Smoke and Cold Blooded, the first two novels in The Birthday Girl Killer series. Drawn to the darker corners of the human mind, she writes psychological crime thrillers that explore identity, obsession, and the thin line between sanity and madness.

Behind Blue Eyes continues her fascination with complex characters, hidden truths, and the unsettling question of whether evil is born, created... or simply waiting beneath the surface.

Diane lives in Greece, where she is working on her next thriller.
