The Teacher's Guide to Spying — Daniel Abbott

"My name is Augustus Fox (well, actually, Gus to my friends ... hello there) and I bear no more relation to an international man of mystery than a quarter pounder does to a cow." Gus is an English teacher, part time carer for an autistic brother, a really rather amateur poker player and soon to be something of the reluctant spy. When a recently arrived Russian gangster asks him to privately tutor his son, MI5 come calling and he soon finds himself caught up in a web of lies and deceit - and, what's worse is that he isn't even allowed to blog about it.
