Death in Kew Gardens by Jennifer Ashley

It all begins when she runs into Mr. Li on the street.  She knocks him down with her parcel and she apologizes.   He does, too.  Then he brings her a present in apology.  She didn't want to take it because she knocked him down.  He insists.  It's a beautiful box of tea.  It tastes like ambrosia.  She loves it. She's shocked when the man next is knifed to death in his bed She is even more shocked when Mr. Li is accused of killing him!

Berkley and Net Galley allowed me to read this book for review (Thank you).  It will be published June 4th.

She's insistent that it wasn't him because he was visiting her at the supposed time of death.  However a witness saw a Chinaman leave the house near that time so Li gets arrested.  Then a Chinese boy is killed in the Kew Gardens.  It was the man's son.  Had he killed his dad?  Kat doesn't think so.  She and Daniel start their own investigation.

In the meantime a new housekeeper has been hired and she's a real pain.  She dislikes everybody and threatens to fire everybody.  They are thinking of quitting anyway.  Kat tries to keep her team together and get rid of this housekeeper as well as try to solve this mystery.

She does solve the mystery but it turns into a knife fight in Kew gardens and you're not sure who's going to be alive at the end...

I had no idea who the killer was.  This was a good mystery!
