A serial killer is terrorizing Dilli and Mughal nobleman and detective Muzaffar Jang might have finally met his match. In the spring of 1657, the Mughal armies have reached the Deccan, besieging the Fort of Bidar. Back home in Dilli, there is unrest: the empire seethes and stirs, and its capital reflects this turbulence. Muzaffar Jang, newly married to his beloved Shireen and trying to adjust to life as a husband, stumbles into the investigation of a merchant's murder. Even as another crime - the kidnapping of a wealthy moneylender's infant son - occurs, Muzaffar finds himself at odds with his brother-in-law, Khan Sahib, the Kotwal of Dilli. Things get increasingly puzzling as one murder follows another and, soon, it is clear that the streets of Dilli have a serial killer on the loose. Muzaffar, who soon finds himself at odds with the system as well as those closest to him, must follow his gut to unmask this audacious murderer, while trying to obey Khan Sahib's warning: do not get in the way of the law. But has he finally bitten off more than he can chew?
