I Know What you Did Last Wednesday — Anthony Horowitz

"It's not fair. I do my homework. I clean my teeth twice a day. Why does everyone want to kill me?"

It's a dangerous life being the younger brother of the world's worst private detective, but Nick Diamond's survived ... so far. Nick's due a holiday, so he should be happy when his brother Tim receives an invitation to a school reunion on a remote Scottish island. But Nick's got a bad feeling -- and it's not indigestion. When he meets their fellow guests, the feeling only gets worse. Especially when they start dying in ever more bizarre ways...

Could the Diamond Brothers' days be numbered?
