SOLVED. Adult SciFi novel 1960's or 70's Re: Corp that invented teleportation devices used on earth and moon under investigation when someone was murdered through sabotage of teleportation device. I read the book 1992-1996. [s]

I believe this book was the first in a series. The copy I had was a small paperback. The cover and first few pages were missing. It was not a very long novel.

All the Colors of Darkness ?

It's about a corporation that invents and runs a network of teleportation doorways, and then a customer goes missing.

I really like Bill's suggestion. Implied there is no murder in that suggestion, however.

Niven has some teleportation murders (iirc), but most of his teleportation booths (and stepping discs) are in the form of short stories, or very backgrounded in Known Space stuff (Ringworld / Fleet of Worlds).

Some of the short stories are in slim volumes. But I think you'd realize they're independent of each other. Only the Gil the Arm, and Beowulf Shaeffer even keep the same protagonist.

_The Patchwork Girl_ (Gil the Arm) has a locked-room mystery of an attempted murder on the moon.

Good morning. I want to thank all of you that responded. I reviewed the suggestions and Bill, you are right. It is All the Colors of Darkness by Lloyd Biggle Jr.

I am most appreciative!
