PI Chris Day is hired to solve the complex double poisoning on the Scarborough family's private Florida island estate. Eighty-five-year-old William Scarborough and an uncle are murdered at the patriarch's birthday party. Everyone is a suspect and Chris has to unravel the crime, doing it in his own "outside the box" way. One murder was twenty years in the making. The other went back many decades. Past sins, sex, greed and revenge take center stage in the double homicides. - See more at: http://christophermatthewspub.com/murder-on-cardita-key/#sthash.3uXDpHDo.dpuf
