I rent a little house on concrete stilts in a coconut plantation on Koh Phangan. The large, studio room has access to the roof space in one corner of the ceiling via a hatch that is covered by a rectangular peice of board that neatly fits that opening.

A few weeks ago, I saw that this rectangular piece of board was open! The board had been pushed to one side. I concluded that perhaps it had always been like that, and I just hadn't looked up previously. So I used a long pole to 'shuffle' the board along until it dropped back neatly into the access opening.

I was away in Pattaya for 5 days and returned to my house yesterday. Walking around, I was shocked to see this hatch open again!! I used the pole to close it again, but am now feeling somewhat apprehensive!

• My house is detached and on stilts - no-one can have access to it or the roof space

• Although I occasionally hear mice in the roof space. n0osmall animal could surely move that board

• No creature (snake, cow , naked woman etc) has ever fallen into my room, and I've never found any evidence of animals in my room.

So what is moving the board? Wind getting under the roof tiles? I think not - the board is too heavy...

Hmm - I don't think I will be able to sleep tonight.....
