It's Christmas at Edinburgh's magnificent Barlinney Hotel, and chief housekeeper Cosmo Grant is in charge of the festivities. He's already got his hands full when handsome Ren Vaudrey checks in. Ren is an accountant, or so he says, and he's asking questions about his missing colleague, Sam.It soon turns out that Ren is an undercover cop. Cosmo wants to help him – Ren is kind as well as handsome as hell – but unless he can do it within the Barlinney's walls, Cosmo is stuck. A victim of crippling agoraphobia, he's been a prisoner in this gilded cage for over a year.There's another problem too. Ren clearly adores his partner Sam. In the face of his rising attraction for this man, Cosmo has to bear in mind that Ren may be already taken. Cosmo gathers all his courage to do the right thing by Ren and Sam – and as a glittering Christmas Eve descends on the city, finds himself confronting his very darkest fears.
