In Case of Hooks, Part 6: "Some Like It Hooks"
If back in your present time, go back to investigating charred remains of your house.
In case of investigation of charred house, find a charred match.
If charred match found, bring it to crime lab so that science can be done at it.
If science is done successfully, find charred fingerprints on charred match.
If charred fingerprints found, then fire was work of local pyromaniac.
In case of pyromania, follow long trail of ashes across city.
In case of ashes leading to building with smoke coming out of the windows, you may be at the right place.
If at the right place, confront pyromaniac inside.
In case of confrontation, pyromaniac may attack you with fire.
In case of fire, break glass on pyromaniac's head.
If pyromaniac is physically stunned by glass attack, take opportunity to lecture him on fire safety.
If fire safety lecture goes on too long, pyromaniac may become bored and/or enraged.
If pyromaniac becomes enraged, he may leap at you.
If pyromaniac leaps at you, close your eyes, swing your hook-hands wildly, and hope for the best.
In case of best, hook swing may literally "disarm" pyromaniac.
In case of worst, disarmed pyromaniac may ignite and now have fire for hands.
In case of pyromaniac having fire for hands, get the hell out of there, because fire is a hook's natural predator.
