Barbara Nadel's gripping Ikmen mysteries are the inspiration behind The Turkish Detective, BBC Two's sensational eight-part TV crime drama series available to watch on BBC iPlayer.

Dark magic is unleashed on the streets of Istanbul . . .

When a newborn baby is found drowned in the shallow waters of the Golden Horn, all-out warfare threatens to erupt between rival criminal gangs. Inspector Kerim Gursel is assigned to the case and he must tread carefully when DNA tests reveal that the baby's father is Gorkan Pasahan, Istanbul's most feared Mafia boss. But the identity of the infant's mother is yet to be discovered . . .

Meanwhile, etin Ikmen and Mehmet Suleyman attend the winter festival known as Bocuk Gecesi, held on the darkest night of the year, and witness a magic trick whereby a young man, Emir Kaya, disappears. While Ikmen investigates how the illusion took place, Suleyman conducts a tortuous hunt for Emir Kaya that exposes a harrowing tale of depravation, betrayal and corruption where the bloodline of a child is worth killing for and everything has its price . . .
