Put one or two out each week for the kids and let them solve (or attempt). Keeps them busy and fully exercises their minds!
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.
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.
