Thanks - yes insurance covers the loss and it could be much worse.

All my doors have a secondary deadlock on them which is why they couldn't open the doors even when inside. The police say this was probably a major factor in them not taking larger items.

Cheeky ****** even spoke to my neighbour.

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
