Where There’s a Will (Nero Wolfe, #8)

While investigating the bizarre will of the late multimillionaire Noel Hawthorne, who left the bulk of his estate to his mistress and nearly nothing to his family including his three sisters, April, May and June, our astute sleuth Nero Wolfe stumbles upon a legacy of murder.

Of course Wolfe has the assistance of Archie Goodwin, his able but opinionated assistant, to help him weave around the roadblocks laid down by Inspector Cramer of the NYPD. Bottom line? It's Nero Wolfe at his best.
