When your future shines bright, you'll find that the world is full of goodwill.
A person died. Dean didn't even need to explain much.
The city's bomb squad took away the explosives. Detrov of the Internal Affairs Department chose to play dead outright, and Harry and Robert didn't even need to be mentioned. The forensics team, led by Holz, arrived later. After a cursory examination of Daniel's body, they concluded it was self-immolation. All that remained was to go through the motions before the case could be officially closed.
This made Dean feel incredibly pleased until an unpleasant person appeared before him.
"Detective Dean, long time no see. The speed of your promotion is astounding," a white man in a suit said with a friendly smile, extending his right hand to Dean as he approached with a female companion. For some reason, the hand he extended was shaking subtly, as if he was quite afraid of Dean.
