Professor Peter Maxwell sets out for one of the Coonskin planets, but his beam is intercepted and later returned to Earth only to find that his beam was actually duplicated, his duplicate has been killed, and his friends (some goblins, a ghost, and a time-traveling Neanderthal among others) have already buried him.

I wonder whether this was the first transporter accident story (which, as we all know, eventually leads to two Will Rikers).
You mean there were two Pete Maxwells?
