In the books
In the A Song of Ice and Fire novels, Ser Wendel Manderly is the second son of Lord Wyman Manderly, the Lord of White Harbor and Warden of the White Knife. He is not quite as fat as his father and older brother, but is still considered immense. He is loud and boisterous, wears a large mustache and is bald.

Wendel was killed in the book similarly to the show: when the massacre started, he rose to his feet, an arrow went in his open mouth and came out the back of his neck, killing him instantly.
