Adayfi is now working on a new book charting the struggles of his post-detention life in Serbia. One wall of his Belgrade apartment is filled with colourful sticky notes describing events that will make up its contents. The notes record interrogations by police, thwarted attempts to make friends and find a wife, and efforts to draw President Biden"s attention to his plight. Every day he communicates with other former detainees - more than 100 in total - across various online and WhatsApp chat groups. Many have faced the same sorts of restrictions as Adayfi.
