A murder in London is carefully staged. No clues are left behind, only a message for one man. So it’s up to the British-Bangladeshi forensic psychologist and legal consultant Daniel Rahman to be called in when the usual investigative techniques have failed. One suspicious death quickly becomes a string of calculated murders, all connected to an age-old financial scandal and a disturbing view of justice. Daniel and Detective Inspector Sarah Miller chase a clue thru the streets of London, the halls of Scotland Yard and into the courtroom, where they face coded messages, psychological tricks, forensic evidence and legal loopholes. It's like the killer knows not only the justice system, but Daniel himself. The investigation feels more personal with every step. Daniel has to interpret behaviour, question evidence and confront the blurred line between justice and revenge before the killer makes his final move. The Psychological Detective is a legal psychological thriller, combining criminal investigation, forensic psychology, courtroom drama and a battle of wits against the darker side of London’s legal scene.
