Pseudonymous Bosch is the anonymous pseudonymous author of the Secret Series and The Bad Books. Not much is known about him other than that he has a passionate love of chocolate and cheese and an equally passionate hatred of mayonnaise. Rumors of Boschian sightings are just as frequent and about as reliable as reports of alien abductions. If you ever meet anyone claiming to be Pseudonymous himself he is almost certainly an impostor. The real Pseudonymous is said currently to be hiding in a cave in a remote jungle (although there are contrary reports that he is somewhere in Greenland).
