Detective comics...

Remember back in the sixties and seventies, toy makers and book publishers jumped at the chance to produce anything connected to a popular TV show regardless of the show's demographic or content. Hence, the kids of those decade were afforded annuals and games based on the likes of such adult shows as 'Z Cars', 'The Sweeney' and 'The Professionals'. Looking back, it does seem odd if not immoral that a show like 'The Professionals' could spawn a kids merchandise bonanza but it did. 

What if modern detectives had their own comics aimed at the junior market?

Yeah, I know 'Murder She Wrote' might be a bit tame for seventies kids but what the heck?
