Chin Yong-Yun Sets The Date, by S.J. Rozan

"Chin Yong-Yun Sets The Date," by S.J. Rozan, in Deadly Anniversaries, edited by Marcia Muller and Bill Pronzini, Hanover Square Press, 2020.

This is the fifth appearance here by my friend S.J. Rozan and the second by the formidable Chin Yong-Yun.  She is the mother of Rozan's private eye Lydia Chin, and quite a character herself.  This aging resident of New York's Chinatown combines the modesty of Poirot, the indecisiveness of Holmes, and the lack of curiosity of Marple. 

In this story she notices that Chu Cai, the son of a friend, seems unhappy, even though he has just gotten engaged. Listen to the way she rationalizes her behavior after seeing the Chu family in a restaurant:

I stood on the corner enjoying the warm day.  Eventually the Chu family emerged from the Wo Hop.  I took a few steps over, to the shadows...  I hurried to catch up with Cai.  Since he had been such a good friend of Am-Zhang's, it was only polite that I greet thim.
"Chu Cai!" I said. "Can this be you?"

 She cleverly arranges for him to come to her apartment to tell his problem to Lydia -- who, alas, is not there.  Perhaps, Mrs. Chin says, he can tell her the problem and she can do the groundwork, although she is not quite sure what ground has to do with detective work.

A wonderful character, a charming story.
