John Watson found it fascinating when his newest patient turned out to be the surrogate of a child for the soon-to-be-married uber-powerful talent agent Simon Pearson and the up-and-coming politician Vernon Laing. But when Simon's business partners start to worry that he's more interested in his husband-to-be's career and not the next big Hollywood actor desperate for some West-End credibility, they decide that there's only one person they can trust to investigate this discreetly.Holmes!But when he rejects their initial overtures, the partners won't take 'no' for an answer. They hire his law firm and Holmes - on the cusp of being made the first non-named partner in the history of Fothergill, Patricks & Havers - finds himself with no choice but to get involved in a messy investigation that touches on many aspects of the modern gay family.Prevented from assisting Holmes due to client-patient confidentially, Watson finds himself wondering why his own family thinks Holmes is so damn wonderful, what church will the 'gay wedding-of-the-season' be held in and what is the right colour tie to buy his boyfriend?But Holmes, as he digs for dirt on Vernon Laing, starts to realise that not everyone is as innocent as they seem and maybe Vernon's the pawn in a clever business plan instead of being the villain.For the fourth time, Holmes & Watson find themselves on another adventure which takes them from the Watson family home in Devon to a retired US Senator's mansion in Provincetown. From Michelin-starred restaurants to hedonistic sex clubs and features more than enough one-liners and inappropriate sexual encounters to keep things going.
