Nero Wolfe is sleuthing as usual in these three mysteries. In the Best Families deals with Mrs. Rackam, an aging millionaire who approaches Wolfe to investigate why her young and penniless husband suddenly and mysteriously has large sums of money. Wolfe's inquiry leads him to a confrontation with Arnold Zeck; later a letter bomb causes Wolfe to resign from detective work and go into hiding, leaving his assistant, Archie Goodwin, to solve the case. Has Wolfe's career ended in humiliation? Only time will tell. Michael Pritchard's clear and strong reading helps support the tale. Rachel Bruner, a wealthy society widow, turns to Wolfe in The Doorbell Rang. She writes him a check for $100,000 and asks him to stop the FBI from spying on her and her family. She will pay more if he is successful.
