In Inspector Singh Investigates: A Deadly Cambodian Crime Spree by Shamini Flint, the titular character is sent from his home in Singapore to Kuala Lumpur to solve a murder case that seems unsolvable. Famous Singaporean model Chelsea Liew is on death row for killing her ex-husband, but both Singh and Liew maintain her innocence. Despite his best efforts, Singh keeps coming back to the same conclusion: Liew had the strongest motive for the crime. Her husband was taking away her children, and she snapped.
 
Singh is determined to crack the case and prove Liew's innocence, but the Malaysian police are uncooperative. They are resistant to working with Singh and seem content to let Liew stay on death row. Nonetheless, Singh pulls out all the stops to solve the case and bring justice to Liew and her children. As he investigates, Singh must navigate cultural differences and political tensions to uncover the truth behind the murder.
