|Book||Fire & Blood (mentioned)|
The disguised Ser Rickard Thorne of the Kingsguard and his charge, Prince Maelor Targaryen, tried to stay overnight in the Hogs Head while journeying to the safety of Lord Ormund Hightower's host at the nearby siege of Longtable. Sly was instructed by the owner of the inn, Ben Buttercakes, to search for coins in Rickard's belongings, but he found Maelor's dragon egg wrapped in Rickard's white cloak instead. When he informed the inn's common room of his discovery, Rickard fled with Maelor, slaying Ben on his way out. Afterward, Sly was hanged from the center span of the old bridge at the command of Lady Caswell.
