This is what I was told when I used my detective on n1
" You wander into Shazam's house and are immediately struck by the fact that the house is empty. Clearly he's out and about at night. You find a book entitled 'Methods of an investigator'. You recognise it, it's one you read before. You make your way upstairs and find a bathroom. There's a lot of hair trapped in the plughole. You would search further, but the screams of LivingAngryCheese interrupted you. You rush out to see what has happened, and are joined by all the town in doing so. You gain no further clues this night."
I think I'm a false detective too. That's why I thought shazam was a detective and trusted him too much.
