For this tip you need to start in Windhelm which is in the top right of the map. You can reach it easily by paying a carriage for about 20 gold.
• Once in Windhelm head to the Aretino Residence and go inside. • You'll find a creepy kid inside who will never turn around from his ritual. • Sneak into the wall behind him, you may need to walk rather than run if your sneak isn't high enough. • Note this is an excellent time to also level up your illusion skill using my video tip on leveling your illusion using muffle shown here http://goo.gl/n0DgN
