Gunsmoke #424, "Marryin Bertha," Marshal Matt Dillon finds himself dealing with an unusual problem when his deputy Chester Proudfoot confesses to a reckless mistake. Suffering from spring fever and feeling romantic, Chester has been writing letters to lonely women advertising in St. Louis newspapers, stretching the truth about himself and even sending one woman Matt's photograph instead of his own. Now a widow named Corinne Gatesley has arrived in Dodge expecting to marry Chester, and the panicked deputy begs Matt to impersonate him and send her away. When Matt meets the imposing Mrs. Gatesley, a woman taller than Chester and built like the Marshal himself, he discovers Chester's letters promised her he had money coming his way.

The situation turns dangerous when Doc Adams recognizes Matt's description of the woman. She may actually be Bertha Hoskowitz, a woman once suspected of marrying and murdering several men for their money in St. Louis, though authorities could never prove it. With Chester having foolishly promised wealth he doesn't have, Matt realizes the deputy may have made himself the target of a cold-blooded killer.
