WITH THE CORPSE

THE corpse was burnt to a crisp. From the clothes to the skin, everything was scorched black. But this was very strange. Could a body really be burned to such a degree in such a short period of time? It's definitely impossible. 

He had been observing the outside of this room for two hours. And no smoke appeared in that duration of time. It only did right after that explosion outside. There's no way this body would turn like this in such a short period of time. Which only meant one thing – this body was already burned before putting it here.

If he wasn't here, staking the place, it might take a long while before anyone found out about the corpse. Maybe it would only be so once the fire spread enough for people to notice. But with the explosion outside, everyone's attention was focused there. Who knew when they would notice this fire?
