So in the middle of the night some random person wrote a message on my front door

Perhaps, 'No canvassing or door to door salespeople' would have been better. You may have offended a lady of the night! 

Jesting side, I understand your feelings on this.

Are you able to fence off your front garden?

We use lights as one of our deterrents - they illuminate all of the ground floor entrances. Once I locate a shop that sells movement sensors, we shall have, instead, flood lights installed. A light suddenly switching on will put off most ne'er-do-wells.

I seems to be a prank depending on what the person wrote.

You need to take some action if the disturbance is regular.

Is the crime rate high in your area or is it just kids mucking around? The timing is interesting. We are usually at our deepest sleep around 3.00am and that's a favourite time for intruders. Again on security, we have security grills at each window and door. They are decorative as well as functional to keep my wife happy. It's important to make sure that you still have easy exit from strategic points in case of fire.

I hope this resolves itself soon, especially as you are often alone. I really would start to do something about security, just in case.

The police presence suggests that other people may have been disturbed and reported it. In your shoes, I would report it to the police too.

I don't know whether you have this where you live, but in the UK police will patrol past your home during the night as a deterrent if there's been a suspected attempt to enter. In Thailand, we can pay a monthly fee for a twice daily patrol. These arrangements are no guarantee but they show that citizens aren't just doing nothing and may deter whoever is up to no good.

Is that window vulnerable?
