We are woken at 6 and counted in the cell. Mine is 12 metres long and just over four metres wide, holding 50 or 60 prisoners, mostly Thais, mostly murderers and rapists. The cell has one toilet, which is a hole in the ground, and poor ventilation. I sleep in a face mask because tuberculosis and pneumonia are common. I've been in this jail for five months, since my arrest in September.

My book, Verisimilitude, was a rather clumsy first attempt at fiction - only 50 copies were printed and seven sold. I love Thailand and respect the royal family. It was never my intention to offend anyone.

For breakfast I have soy milk and a biscuit. The prisoners wash and shave around troughs covered in grime. The water is changed once a week. Then there's assembly. We stand to attention as the Thai flag is raised. We're asked to pray to a large gold Buddha. I use the time to collect my thoughts and think about my loved ones.
