Dead to the Last Drop (Coffeehouse Mystery, #15)

From Cleo Coyle, the  New York Times  bestselling author of  Once Upon a Grind , comes an exciting new installment in the "highly satisfying"* Coffeehouse Mystery series. ( *Publishers Weekly)
  
When the White House asks coffeehouse manager and master roaster Clare Cosi to consult on a Rose Garden Wedding, she uncovers long-simmering secrets that threaten to boil over...
 
Clare's Washington visit is off to a graceful start, when she lands a housesitting job in a Georgetown mansion and is invited to work on the Smithsonian's salute to coffee in America. Unfortunately, her new Village Blend DC is struggling--until its second floor Jazz Space attracts a high-profile fan in the daughter of the President. But as Clare's stock rises, she learns a stark lesson: Washington can be murder.
 
First a State Department employee suspiciously collapses in her coffeehouse. Then the President's daughter goes missing. After another deadly twist, Clare is on the run with her NYPD detective boyfriend. Branded an enemy of the state, she must uncover the truth before her life, liberty, and pursuit of happiness come to a bitter end.
