SOLVED. Hispanic detective in LA mystery series. He relaxes listening to Bach fugues. [s]

[scherzo♫]

Mystery series set in LA with Hispanic detective (Lieutenant ?)
Female author, I think
Detective has wife and a couple of young children ("hostages to fortune")
Detective relaxes by listening to Bach fugues
Read in late 1970s

[Sharon]

That far back, I'm wondering if it is the series by Dell Shannon with Lt. Mendoza. His wife is a redheaded Irish girl and they have twins. Quite a lengthy series.

I'm thinking that you are right Sharon. I can't think of another one that is set in L.A. with an Hispanic detective that's that old either.

Yes, Dell Shannon and Lt. Mendoza!
Thank you.
