The Golden Spiders is a 1953 Nero Wolfe mystery novel by Rex Stout. I'm working my way through this entire (and entirely enjoyable) series.
from the back of the book:
Nero Wolfe was almost as famous for his wealthy clients and extravagant fees as for his genius at detection. So why has he accepted a case for $4.30? And why have the last two people to hire him been ruthlessly murdered? Wolfe suspects the answers may lie in the story of a twelve-year-old boy who turns up at the door of his West Thirty-fifth Street brownstone. In short order, Wolfe finds himself confronted by one of his most perplexing and pressing cases, involving a curious set of earrings shaped like spiders dipped in gold. The case is all boiling down to a strange taste of greed -and a grumpy gourmand's unappeasable appetite for truth.It was adapted as part of the television mystery series that starred Maury Chaykin as Wolfe and Timothy Hutton as Archie Goodwin. You can see it here:
I do wish that television series, with its perfect casting, had gotten more seasons.
Another adaptation of this book in a 1981 series starred William Conrad as Wolfe. It can be seen here:
