We are pretty much definite it was one burglar who came in. I expect if I had got up sooner they would have legged it. The most common response by far, the police said. The last thing they want is confrontation. What is properly scary is that it took us 10 minutes to get through on 999.
With that in mind, various trophies and stuff are now positioned around the house, just in case. Not sure I'd be brave enough to clobber a burglar, but just in case we are.
Mark won't be leaving his keys downstairs again. Fortunately I am far more careful with mine.
Disklok fitted and Ghost being installed tomorrow. Obviously anti snap locks fitted by locksmith last Saturday. Will think about posts too.
