Trygve Yamamura

To add to the information about Yamamura:

his small office is above a drug-store in downtown Berkeley;

the door is marked TRYGVE YAMAMURA, PRIVATE INVESTIGATOR;

he has a wife, five young children, a beautiful Chinese secretary and a degree in criminology;

he is retired from the city police and careful to remain on good terms with them;

he drinks little and does not carry a gun;

he was in the Army and is a Buddhist.

I had completely forgotten the wife, children and secretary who might be mentioned only once in the first novel.
