Trust Your Eyes -- Linwood Barclay

Trust Your Eyes is one of those high-concept thrillers that can be summed up in a few words: Rain Man meets Rear Window.   Thomas Kilbride is a guy who sits at his computer all day looking at Whirl360 (think Google Earth) while in the process of memorizing every street in the world.  You want to know what's at a certain address?  If he's been down that street, he can tell you exactly and in precise detail.  Then one day he notices something strange in a window, zooms in, and discovers that it's someone being murdered.

Thomas' father has recently died in what appears to be a bizarre accident, so brother Ray is home to settle the estate and to figure out how to take care of Ray.  When Thomas tells him about what he's seen, Ray's skeptical.  Who's going to believe someone like Thomas?

But Thomas is right, of course, and thus begins a story that has plenty of twists, turns, and surprises.  What I've mentioned is the merest outline of part of the setup.  Buckle up for a wild ride.
