Clara Fox is at the center of two mysteries: 1) one of her employers accuses her of stealing $30,000 of company monies and 2) she asks Wolfe to help find an associate of her deceased father and recover monies promised when he was a member of the Rubber Band.
The Rubber Band was a group of 6 men who, 40 years previously, helped an Englishman escape the law in Silver City, NV in return for possible rewards if he inherited a part of his family's wealth in the future. Time has passed. Clara has found two survivors of the band and the daughter of another. Together, the four have located the Englishman who is now a peer and extremely wealthy. They ask Wolfe to help them prevail upon the Englishman to fulfill his promise.
Before long, two men are murdered and the lives of two women, including Clara, are threatened. The two cases appear related and people are not what they seem.
This is an early Nero Wolfe, but it has all the classic ingredients. Wolfe stays in his office/home and directs Archie, his assistant, and a group of hourly wage PI's. He never misses a meal or his two daily sessions with his prize-winning orchids in the greenhouse on the roof. The police and district attorney come to his office to threaten and cajole. But Wolfe sits and thinks and solves the cases.
This is a great mystery (as are all Nero Wolfe mysteries). It is well constructed--events are carefully interwoven and characters are unique. It relies on interrogation, deduction, and intellectual prowess not DNA, forensic evidence and violence. You can follow along and see if you can find the killer.
