Colin Pendragon's reputation as a brilliant detective is undisputed in Victorian London. But when murder strikes inside the closed ranks of Her Majesty's Guard, he must penetrate a wall of silence and secrecy to discover the dark truth. . .
After a captain in Her Majesty's Guard and his young wife are brutally murdered in their flat, master sleuth Colin Pendragon and his partner Ethan Pruitt are summoned to Buckingham Palace.

As the minutes tick away, the pressure--and the danger--mounts as Pendragon's integrity is on the line and a cold-blooded killer remains on the streets. . .
