Knave. Joker. Queen. Lucifer Box is back!

The hero of The Vesuvius Club and The Devil in Amber returns with an artistic licence to kill, and the deadliest mission of his career. A new Queen has been crowned, an old enemy has resurfaced and the world is about to be embraced by the lethal wings of the Black Butterfly....

Lucifer Box. He's tall, he's dark and, like the shark, he looks for trouble.

Or so he wishes. For, with Queen Elizabeth newly established on her throne, the now elderly secret agent is reaching the end of his scandalous career. Despite his fast-approaching retirement, however, queer events leave Box unable to resist investigating one last case....

Why have pillars of the Establishment started dying in reckless accidents? Who are the deadly paymasters of enigmatic assassin Kingdom Kum? And who...or what...is the mysterious Black Butterfly?

From the seedy streets of Soho to the souks of Istanbul and the sun-drenched shores of Jamaica, Box must use his artistic licence to confront and kill an enemy with its roots in his own notorious past. Can Lucifer Box save the day before the dying of the light?
