Death Over the Garden Wall

Three modus operandi to die. Four employees, six house guests, and not a single witness.
 
Confusing clues and no helpful leads cloud the death of Countess Giada Barese, who washed up on shore two weeks after her mysterious disappearance.  Henri and Jamie have no idea if her death is a homicide, suicide, or accidental death, for nothing adds up. 
 
There is something strange going on, though, Jamie’s sure of that. The countess was found wearing mismatched slippers, her lover disappeared the next day, and everyone is acting shifty. 

Jamie feels like she’s playing a game of Clue, one she’s determined to win. Where’s a candlestick when you need one?
