A friend of mine (not in ED) had her house broken into. There is a 50 second delay before their burgaler alarm goes off. In those 50 seconds the robbers managed to go from the backdoor to her bedroom and steal gold jewellery that is kept in a drawer. Nothing else (plasma tv, camera, camcorder, Xbox, car keys) was touched. It had to be an 'inside job' - a divorce would be too expensive, it would be a bit harsh to blame her 2 year old, so that just left the cleaner, whom she sacked.
