"You can try ringing the bell there," Rich nodded. "Easier to use the phone in your flat and call down. There's a list of numbers for you. If I'm someplace with too much magic about, where my mobile just won't work, my service will answer and get a message to me."
"You can't feel the wards because you aren't keyed to them. Each building in the neighborhood is warded, the spell work built into the wood and stone itself. Had to do it that way because this is a mostly muggle neighborhood and people have computers, televisions, mobile phones, things like that. Then each flat has separate wards that can be controlled by the occupant. Level one just keeps an eye on things and will let you know who is about. At level five, if somebody tries to force entry, well, you'll have some ashes to sweep up. In addition, this flat, first bedroom at the top of the stairs, has a warded room. Since there's just you I had it set up as a charms workshop."
He grinned. "All the wards were done by a master with my own humble assistance and are pretty well locked in. There's even physical keys. Doubt you'll find any holes. Don't care what additional protections you put up as long as it doesn't muck up anybody's electronics. Hold the keys in your left hand and put your right hand flat on the wall next to the door."
