I think this book was one of the best story in all the Diamond-Brothers series I've read because the second story was very interesting. The story was about a mystery about murder. Tim was invited to a high school reunion, held by a guy named Rory McDougal. However when Tim first arrived at McDougal's private island with his brother Nick and his other past-friends, McDougal was found dead. He was stabbed by something. And day after day when Tim and his friends stayed in the residence, somebody died when no one was looking. Then, Nick, who was smarter than any other people in the room (which was quite silly), found a pattern. Everyone died with something related to the best subject they did in high school. For example, a woman named Janet always came first in French, so she died by being stabbed by an Eiffel Tower model. Brenda died by being hit by and organ, because the always came first in music. Later, it turned out that the murderer, Nadler, who always came into 2nd in every, used all those remote controllers to kill everyone, and everything was planned. In the last, only Tim, Nick, and a guy named Eric survived, and they arrested Nadler and went back to land. I think why I liked this story so much was because every moment was providing suspense. Every time when someone died out, it was scary, and at the same time, the range of who the criminal was was being smaller and smaller. I was so interested. I kept reading this book even though it was passed my bed time. Later, it turned out that no one in the members invited to the reunion was the murderer, so that was another reversal. Furthermore, I want to praise Nick for being calm even though the murderer was very close, taking care of his brother, and solving the mystery in the end.

Two books in one.

I admire Horowitz for the way he can make every line a joke. His cannon fodder of Tim dies helps with this. Nick is slightly too smart for his own good.

The Blurred Man is action packed and I admit I missed a huge clue during it. Well worth reading.

I Know What You Did Last Wednesday is a whodunnit. I admit I had the right suspect in my head but not quite the why-done-it. Entertaining and full of dead bodies.

Definitely worth reading both!

First read these books years ago when I was in primary school & I recently discovered them again. Reading it felt like I was back to my younger self, staying up late to read horror-comedy.

Both books are surprisingly hilarious for children’s stories & the horror/mystery element is extremely gripping, although can be predictable. Some of the jokes are a bit cringe but that just boils down to me being too old to appreciate them lmaooo

Both of these stories are really good. However I prefer I know what you did last Wednesday I was simultaneously hooked and terrified while reading.
