The Blurred Man
The man in the photo is so blurry, it's impossible to make out what he really looks like. And that's before he was run over by a steamroller!

I Know What You Did Last Wednesday
When the Diamond Brothers receive an invitation to a school reunion on a remote Scottish island, things seem to be looking up. But Nick's got a bad feeling, and it's not indigestion. And when he meets their fellow guests, the feeling only gets worse - especially when they start dying in ever more bizarre ways!
