The first book in the Hardy Boys® series, 'The Tower Treasure' proved to be a classic, fast-paced mystery. Characters don't have much time to be developed making them seem a bit impersonal and vague. Also, the plot seems to move too quickly for the reader to become involved in the suspense. Excitement and a surprise ending do help to redeem this story for me. Overall, 'The Tower Treasure' is an intriguing mystery. I still heartily recommend this novel for those who like a fast-paced mystery.
