Pantheon Books is off to a good start at making Scottish-American philosopher Elizabeth Dalhousie as much of a household name as Precious Ramotswe, the female PI in Botswana. Both are creations of Alexander McCall Smith, and Dalhousie stars in the first installment of the author's new series, The Sunday Philosophy Club. The book went on sale at the end of September and is in its eighth printing, with 176,000 copies in print. The five books in the Number One Detective Agency series have more than 3.5 million copies in print combined. Smith plans three more titles for that series.
