The Ultimate Dark Wizards Ultimate Guide to Never Being Caught

Step 1: Choose a location that matches your interests, it can be anywhere you want. Just make sure you like it. I suggest a nice manor in the English country side. Fill it with lots of things to keep you occupied as you may have lots of time on your hands. (House elves may come in handy for things like grocery shopping)

Step 2: Cast the Fidelius Charm on someone.

Step 3: Have them tell you the address of the place now secured in their soul. Guarantee you are the only one around.

Step 4: Avada Kedavra. You are now your own secret keeper. Go do all your evil deeds and have fun!

Step 5: If any Aurors come after you just apparate right onto your doorstep! Make sure they aren't touching you!
