Death in a Budapest Butterfly by Julia Buckley

They are serving high tea to Hungarian women in their tea house.  Almost all the women are elderly and polite.  What she notices is that the special teacup she has on display is being used by one of the women.  She doesn't know why.  Then the woman drinking the tea walks quickly back to the bathroom.  When she checks to see how she's doing, she finds her on the floor against the wall dead!

Berkley and Net Galley let me read this book for review (thank you).  It will be published July 30th.

When the emergency personnel and police show up, the tea party ends.  Everybody has to remain to speak to the police.  The detective asks Hana, her mother and her grandmother to sit in on the questioning and interpret the Hungarian the ladies throw into the conversations.  They do but they can't believe one of these guests would commit murder.

Hana finds herself attracted to the detective.  She helps him with the investigation and then discovers he's attracted to her, too.

Together they work on piecing the facts together.  Hana is the biggest help.  When the killer is identified, everyone is shocked.

I really enjoyed the detective and Hana team action and I hope there will be future cases with this team.
