Just a great mystery.  Aunty Lee is a fantastic sleuth protagonist and the cast of recurring characters in this series is great... I am crushed to be done with these books, as it seems this was intended to be the fourth and final installment. 
 Yu's Crown Colony series is also good, but feels quite a lot gloomier and just don't hit the same so far.  I see a lot of cozy mystery series that should have stayed individual novels, but this one I think could have gone on to 10, 15 books without feeling stale since Ovidia Yu doesn't seem to be runnning out of good mystery plots.   I'll just keep crossing my fingers that she gets a whim to revive Aunty Lee one of these days!
