I read a book a while ago in which a device is invented which opens up "tunnels" back through time. These tunnels cannot be traveled through, but can be used to view what happened in the past. I believe it starts out narrating the invention of the device, then skips ahead to after it is widely in use. There is another device created, a cloak of sorts, which hides the user from the view of someone using the tunnel device. Does this ring a bell with anyone?

That's almost certainly The Light of Other Days.

Arthur C. Clarke and Stephen Baxter were co-authors.

  • Ah, that sounds right! I love books that address the social implications of scifi technology.
