The first time we met Jason Davey, he was entertaining passengers aboard the Alaska cruise ship Star Sapphire, Eight 'til Late in the TopDeck Lounge.
Then he came ashore, got a gig playing lead guitar at London's Blue Devil jazz club, and gained a certain amount of notoriety tracking down missing musician Ben Quigley in the Canadian north.
Now Jason's back again, this time investigating the theft of £10,000 from a dancer's locker at a Soho gentlemen's club.
Jason initially considers the case unsolvable. But the victim, Holly Medford, owes a lot of money to London crime boss Arthur Braskey and, fearing for her life, has gone into hiding at a posh London hotel.
Jason's investigation takes him from Cha-Cha's and Satin & Silk (two Soho lapdancing clubs) to Moonlight Desires (an agency featuring high class escorts) and finally to a charity firewalking event, where he comes face to face with Braskey and discovers not everything Holly's been telling him is the complete truth.
As he becomes increasingly drawn into the seamy underside of Soho, Jason tries to save Gracie, his band-mate's 14-year-old runaway daughter, from Holly's brother Radu, a ruthless pimp, while at the same time protecting Holly herself from a vengeful Braskey - nearly losing his life, and Gracie's - in the process.
