"Immune to Murder" is a Nero Wolfe mystery novella by Rex Stout, first published in the November 1955 issue of The American Magazine.

They have been invited at the request of Theodore Kelefy, ambassador to the United States from a foreign country with large oil reserves, so that Wolfe can cook a dish of freshly-caught trout for a meeting of dignitaries at the lodge.

The next morning, Bragan, Ferris, Kelefy, Papps, and Leeson set out to fish on different stretches of the river that runs through the property, in order to catch trout for lunch.

After Wolfe starts to cook, Archie goes fishing on his own and finds Leeson's body, showing signs of a fatal head injury.

District Attorney Jasper Colvin questions the group and begins to concentrate on Wolfe and Archie, hinting that someone may have hired them to kill Leeson.

They are interrupted by Ferris, who threatens to tell the state attorney general of Bragan's attempt to influence Kelefy and Papps so that the negotiations will turn in his favor.

Wolfe deduced that Kelefy had caught a creel of trout earlier in the day to allow him time to get the firewood piece and take Leeson by surprise.

Kelefy, Adria, and Papps leave the lodge to return home, Wolfe gives the ring to Colvin, and he and Archie depart for New York.

Interviewed by Publishers Weekly upon being named a Grand Master by the Mystery Writers of America, Kaminsky was asked about his work on Nero Wolfe: I ended up writing the last episode, "Immune to Murder," based on one of Rex Stout's short stories.
