EVEN GREATER LONDON, 1887.

An uninterrupted urban plane encompassing the entire lower half of England and, for complex reasons, only the upper third of the Isle of Wight. The immense Tower casts electricity through the sky, powering the mind-boggling mechanisms of the city. The engineer-army of Isambard Kingdom Brunel swarms across the capital, building, demolishing, and rebuilding whatever they see fit. And at the heart of it all sits the country's first private detective agency.

Archibald Fleet and Clara Entwhistle hoped things would pick up quickly for their new enterprise. No-one is taking them seriously, but their break will come soon. Definitely. Probably.

Meanwhile, police are baffled by a series of impossible bank robberies, their resources absorbed by the case. Which means that when a woman witnesses a kidnapping, Fleet-Entwhistle Private Investigations is the only place she can turn for help. They're more than happy to oblige!

But what's the motive behind the kidnap? As Clara and Fleet investigate, they find more than they could ever have imagined . . .
