Garvey

Garvey is an Expert-level Sneak trainer generally found standing at the entrance to The Warrens, a series of tunnels underneath Markarth where the poor and impoverished sleep.

Interactions
On the Dragonborn's hunt for information on the Forsworn agent, Weylin, Garvey can be persuaded, intimidated, or paid to relinquish the key to Weylin's room.

If questioned about Weylin himself, Garvey seems less concerned about Weylin's murderous deed than who will occupy the Redguard's room next.
