Hi, Im looking for a book I read when I was younger, it was a collection of short (2 or 3 page) mysteries, and at the end there would be a question involving the story and the reader would have to use the information given to solve the mystery.
At the end of the story, the answer was given, I believe the answer was printed upside down.

For example:
In the ending of one story I remember, a man (lets call him Bob) drives up to another man's house (call him Mike). Mikeis standing outside and his child is sitting happily on the hood of his car.

For whatever reason, the story calls into question Mike's whereabouts during the last few hours, and he tells Mike that he just got back from a 3-4 hour drive from somewhere. The question at the end was something like "How did Bob know Mike was lying?" and the answer was because if Mike really had been driving that long his car would have been very hot and his child wouldnt have been happily playing on it.

Any information would be greatly appreciated!
