This page contains IGN's Walkthrough for Where Children Toil, Toys Waste Away, the fifth main quest of The Witcher 3's first DLC expansion, Blood and Wine.

To the Shoe Shiner

After wrapping up La Cage au Fou, make your way back to Beauclair and head to the marker on your map to make your way to the bootblack. Looks like some hoodlums are giving the young boy some trouble, so beat them down and send them on their way.

Talking to the boy will reveal the whereabouts of Dettlaff van der Eretein, but it will come at a price. After asking for 500 in coin, wager with the boy for a more reasonable price. Going 350 or lower will get him annoyed, while something like 425 will get him to talk. Or, you can avoid all this by having a level 2 in Delusion.

Exploring the House

Anyway, after getting the information, follow Regis to the nearby home by the docks. Enter inside and start using your Witcher Senses to find clues as to where Dettlaff might be and why he is out being the murderer that he is! There is not much to see downstairs, so head on up to the attic.

Examine the notes sitting over the hole overlooking the lower floor to show a cutscene, then grab the suspicious letter on the desk to the right to get all the information you need. From there, the next main quest mission Wine is Sacred begins!
