Books like Alfred Hitchcock's Solve-Them-Yourself Mysteries

I've owned this book for a number of years but hesitated in reading it because it's a bit old (the 1986 is an edition date, but the writing is from 1963) and I figured that the clues would involve technologies that were popular back then, but not common/relevant 50 years later. While this proved true, I still found the cases enjoyable. For example, one case involves a clockmaker who was attacked while winding all the clocks in his shop. As this book is aimed for the preteen audience, I'm not sure how many of today's kids know what winding a clock is, and if they do, it may only be in the context of winding a travel alarm. Unless you luck into noticing one specific clue in this case, it cannot be solved without the knowledge of semaphore, and I would guess even fewer kids know about that than they do winding clocks. Of the 5 cases, I felt the solutions got more abstract as the book progressed, with the initial one set at a circus and the clock one being easy to solve, but the final one involving 2 kidnapped children used manipulations of words such that even at 29, I still couldn't tell how a solution was reached based only with the clues. Therefore, an OK read, and the cases are short and fun, but a bit dated with odd clues that may or may not help you solve them.
