Capers
Oh um just so you know there are certain Capers you can do for this quest to get the full rewards and extensions to the Thieves' Guild. The rewards the capers give are very handy (such as better loot from people, crafting shop in Varrock). Some of these capers require a certain level (such as 62 thieving for the last caper). The capers I guess can add up to be one quest.
