Perfect for fans of Peter James, Ian Rankin, and Lynda La Plante

START AT THE BEGINNING. THREE LONDON CRIME THRILLERS. DETECTIVE CHIEF INSPECTOR ISAAC COOK'S FIRST CASES.

Meet DCI Isaac Cook as he takes on his first major investigations—a missing actress with deadly secrets, a thirty-year-old corpse in a fireplace, and a methodical female killer carving numbers in blood. From the glamorous world of television to family secrets buried for decades to a serial killer stalking London's streets, Isaac proves why he'll become one of the Met's finest detectives.

MURDER IS A TRICKY BUSINESS (Book 1)

A soap opera actress vanishes. Again. The executive producer wants her found. The eavesdropping assistant knows something. The co-star who played her brother acts suspiciously. DCI Cook is pulled from more important cases to search for a woman with a history of disappearing. But this time, the secrets she's hiding are worth killing for.

MURDER HOUSE (Book 2)

A corpse in the fireplace. Hidden for thirty years. The old house has changed hands multiple times, but someone always knew the body was there. The main suspects are elderly and dying—or already dead. Family loyalty runs deep, and dirty laundry stays private, even if it means a murderer escapes justice. Isaac must break through decades of silence before the truth dies with the last witness.

MURDER IS ONLY A NUMBER (Book 3)

She carved the number 2 in blood on his chest. But this was her first victim. A woman stalks London, killing men methodically and keeping count. The numbers don't add up, and DCI Cook must decode her deadly arithmetic before she completes her tally. She's always one step ahead, disappearing in plain sight, documenting each murder with chilling precision.
