Channel 4's new thriller Suspect features an ensemble cast of would-be suspects, as a detective investigates his daughter's death.


The series cast is led by James Nesbitt (Cold Feet), alongside the likes of Loki star Richard E Grant and Outlander's Sam Heughan.

According to the broadcaster's synopsis: “When veteran detective Danny Frater (James Nesbitt) turns up at a hospital mortuary for what he thinks is a routine ID check on a young woman’s body, he gets a devastating shock; the corpse turns out to be his estranged daughter, Christina (Imogen King).

“He sets out on a mission for the truth, retracing her last days and hours, in an agonising crusade to discover what really happened to his only child.”
