The corpse of a mild-mannered tailor working on Savile Row is found in a wooded corner of a park in London's tony Mayfair district. On his body is The Organization's telltale 'calling card,' a signal that the sinister cult is preparing to launch its next terror plot against the people of Great Britain.

Dalton Lee and his team of architect/detectives arrive in London to find an abundance of suspects whom The Organization could have embedded in the victim's life: an ex-girlfriend and her mysterious shop assistant, a belligerent bocce competitor, a work colleague with great disdain for the deceased, as well as waitresses he befriended, and a customer he angered.

A swatch of silk in a tree branch, footprints in the mud, and a plea for help left on a restaurant napkin all seem to be clues as to who murdered Antonio Tinti . . . and how his seemingly quiet life intersected with the plans of international terrorists. But can Lee and his team determine who the murderer is before The Organization's horrific scheme starts to unfold?

As he did in Manhattan and Miami, Dalton Lee becomes obsessed in Mayfair with an architectural detail – this time, the fence surrounding the scene of the murder. However, at the very moment Lee deduces who assassinated the tailor, he and his colleagues within Scotland Yard learn they've been distracted from the actual terror plot that's about to get underway.

A fickle fog, red sprites in the night sky, sculptures that talk, and a clandestine meeting in a creepy carnival ground combine to make Murder Becomes Mayfair an eerie, atmospheric adventure that's set against the backdrop of London's spectacular architecture.
