The No. 1 Detective Agency Series - McCall Smith

Alexander McCall Smith:

[No. 1 Ladies’ Detective Agency” series: featuring Precious Ramotswe -- Botswana's leading, and only, female private detective.]

• The No. 1 Ladies' Detective Agency
• Tears of the Giraffe
• Morality For Beautiful Girls
• The Kalahari Typing School For Men
• The Full Cupboard of Life
• In the Company of Cheerful Ladies
• Blue Shoes and Happiness
• The Good Husband of Zebra Drive
• The Miracle at Speedy Motors
• Tea Time for the Traditionally Built
• The Double Comfort Safari Club
• The Saturday Big Tent Wedding Party

There is nothing objectionable for a pre-teen, but I do not think they would find them very interesting.

McCall Smith has several other series; none of them are anything like these.
