Rum Affair [EPUB ebook] 
Dolly and the Singing Bird ; The Photogenic Soprano

This mystery is told from the point of view of the ‘Bird’; Tina Rossi, a famous coloratura soprano who arrives to sing at the Edinburgh Festival, only to find a murder victim in a cupboard, whilst at the same time her lover, top scientist Kenneth Homes, has gone missing. Saved from the long arm of the law by Johnson Johnson, a world renowned portrait painter and enigmatic solver of mysteries, Tina joins him on a yacht race to the Hebrides – there are connections anyway as Homes was conducting top secret research in the area. Here, though, there is yet more trouble and the mystery deepens as Johnson’s yacht ‘Dolly’ nears the island of Rum, where it turns into a race for life rather than prize money. This is the first title in the Johnson Johnson series and in common with the remainder involves an intricate plot and solution which is far from immediately obvious.
