Deadly Dance Lessons: A Senior Sleuths Cozy Mystery Series (short reads). The Sunset Manor Mystery Series, #6

Deadly Dance LessonsWhen a handsome ballroom instructor arrives at Sunset Manor promising to teach residents the foxtrot, retired principal Violet Hartwell smells trouble faster than Frank Morrison can rev up his souped-up mobility scooter. Ricardo Suave (clearly a stage name) is too charming, too interested in residents' valuables, and far too evasive about his background for comfort. But before the Sunset Manor Detective Agency can waltz their way through a proper investigation, their dance lesson turns deadly.
The disco ball comes crashing down in a shower of mirror fragments and twisted metal-and Ricardo's perfectly timed dodge suggests this was no accident. Armed with Violet's vintage leather investigation kit, Frank's questionable DJ equipment, and more determination than sense, the team must catch a killer before he strikes again. But between sabotaged ceiling fixtures, insurance fraud schemes, and the upcoming "Dancing with the Staff" competition, they're going to need all their detective skills-and some serious dance moves-to survive.
Because at Sunset Manor, even recreational activities can be lethal. Will the detective agency solve the case in time for the competition, or will their final dance be with death itself?
