A story having a tragic twist doesn’t automatically make it inappropriate for kids.

I wonder what dr detroit did wrong to be bombed into oblivion; he is not fully wrong. As an example, the HCA story 'tinderbox' is clearly built from earlier borrowed cloth. As a dane myself, it is apparent that HCA didn't even have a danish term for the demon dogs, so he just calls them 'dogs' to avoid issues with his audience.
