The excellent heist 'em up, Monaco: What's Yours is Mine, and the game that really put Telltale's brand of storytelling on the map, The Walking Dead, are both currently free and available to one and all on PC.
Monaco is available until 6pm BST / 7pm CEST tonight (that's September 8) over on Steam, with developer Pocketwatch Games preparing for the imminent launch of its next game, a rat-themed controller-based RTS called Tooth and Tail. The Walking Dead, meanwhile, is currently available for free over on the Humble Store, a promotion that ties into the end of its summer sale. You'll have to grab that one before 6pm BST / 7pm CEST on September 9.
