A great collection of mysteries, brain teasers, and conundrums featuring Dr Haledjian. Overall, it's a great book for those who like to puzzle things out, or for those who want to build their ability to grab details.
Put one or two out each week for the kids and let them solve (or attempt). Keeps them busy and fully exercises their minds!
The quick-read format and the mental challenge of solving the mystery before coming to the end of the story were well worth the time devoted to reading.
