In the early 1960s, the Science Fiction Book Club offered a book with a plot about a transporter company which initially couldn't get the transporters to work.
Because they had so many false starts, when they finally opened in Manhattan they couldn't get any press to come to the opening.
They begin operations and become enormously popular. As I remember it, you step into the equivalent of an elevator, the doors close, then open and you're at the new location.
But then someone doesn't show up at the other end and is lost in space. And it may have been some kind of conspiracy that this "accident" happened.
Or something like that.
Anyone know the name of this novel?
