In the Best Families (Nero Wolfe Series)

Nero Wolfe and his capable assistant, Archie, help a rich old lady uncover the mysterious source of her husband's money. The case leads them unexpectedly to the country's most dangerous man. And if the sleuths want to live, they'll have to consider an alien idea: run and hide. That will be no small feat for the wide Mr. Wolfe.

"The Master of Detection strikes again. Delightfully puzzling." (B-O-T Editorial Review Board)
