DS7 has read lots of Famous Five, Five Find-Outers, Malory Towers, Just William etc. This weekend he's been reading Poirot's casebook which contains short murder mysteries.
I'm just wondering if these are actually suitable, given his age. I remember reading them in late juniors, but he's still in the infants and they are, after all, about murders, though they're not gruesome and the baddie always gets caught and punished so hopefully they're not morally bad (occasional racism, classism and sexism - which we will discuss - aside).
AIBU to let him read them, and if so, can people suggest alternatives please?
He's not really into fantasy or magic or animal stories. IIRC he's got a reading age of 12+ and enjoys Horrible Histories, Asterix, Obelisk, Enid Blyton's mystery and school stories (not SS, which are "boring and too slow"), Just William, some Jacqueline Wilson (avoiding the scarier ones). He wants to read Biggles, but I've said that's too violent.
