John Sinister is not having a good week.
Hired to look into some shady goings on at the airship factory, his investigation has barely begun before people start dying. Soon he's on the wrong side of some fairly unpleasant people, and that's before he meets Dexter, the world's only walking, talking, mechanical cat. That's when things get complicated.
With secret societies, arrogant aristocrats, and criminal chocolatiers to contend with, John and Dexter will have to keep their wits about them if they're going to come out of this alive. And if John happens to fall in love with his employer's daughter along the way, well nobody said catching a killer was going to be easy now did they?
