There were several 'stories' to a book, and they were all puzzles you had to figure out. A story was told to you as if you were some sort of law officer, but I don't remember if you (the reader) were actually a detective or police officer, or maybe even a judge or jury deciding a court case.
One story in particular I remember: Person tells you they were standing outside a tent at night and saw something bad (probably a murder?) happen inside, so they know who the killer is. They tell you there was a lantern hanging at the top of the tent, so they saw the shadows on the tent walls. The "answer" to the puzzle is that (view spoiler)[this person couldn't have seen what was happening because a lantern hanging above would cast shadows down, not against the tent walls. (hide spoiler)]
Another story involved someone hiding in a stream/lake and using a straw (maybe a hollow reed?) to breathe underwater. I believe this person died, and you had to figure out what killed them. The answer is that (view spoiler)[the straw was too small a diameter for the length of the straw, so the person breathing was unable to exhale all the CO2 and inhale fresh air, and they suffocated.
