How To Complete Hush, My Darling in Kingdom Come Deliverance 2

Talk to Martha
Find Martha in the house attached to the forge in the southeastern part of Miskowitz. Speak with her and offer your blacksmithing services. Accepting her request initiates the quest. If you haven't already, you can also speak to the bailiff nearby about Matthew (of the Dry Devils group) to potentially find Martha more easily.
Craft Horseshoes

You may already possess the necessary materials: two Farmer's Horseshoes. If not, gather two pieces of Scrap Metal and craft them at the forge. Return the horseshoes to Martha.
Find Victoria

Martha will ask you to deliver the horseshoes to Victoria, whose house lies south of the forge. Upon entering, you'll discover blood. Inspect it to trigger the next step. Report your findings back to Martha. She'll suggest searching Sigismund's camp.
Sigismund's Camp

Located south of Opatowitz, this camp may also hold Matthew (Dry Devils) if you are still searching for him. Speak to the blacksmith about Victoria; he'll mention a soldier named Black. Find Black in the infirmary tent – he's ill.

Black requires medicine before talking. Provide him with a Digestive Potion (craft one if needed). After a couple of hours for the potion to take effect, he'll reveal Victoria's likely location in the eastern woods. Find her at the quest marker.
Speak with Victoria to resolve the situation. Dialogue choices have minimal impact on later events. However, promising Victoria Black's protection (if you made him promise it) offers a hopeful conclusion. Completing this conversation finishes "Hush, My Darling." Continue with main quests or explore side quests like "In Vino Veritas."
