In The Jennifer Morgue, Bob Howard's middle names are revealed to be Oliver and Francis, making his full name Robert "Bob" Oliver Francis Howard. If we take Bob as the first name, his initials become BOFH. Later on, in Pimpf, the reference is strengthened by the appearance of Peter-Fred Young, the PFY.
The series has plenty of jokes on names (see Pinky and the Brains, TLA IPO, Mabuse, ...). But was this joke intended from the start, or was this a retcon? Are there hints before The Jennifer Morgue about BOFH, in the books or in author interviews etc.?
