phoenix was in the office when a letter saying "dear phoenix here is your fixed assets and liabilities income expenditure and stuff for 2016 (and it says more boring stuff too)"
phoenix had no idea what it was so he called his accountant and he told him it was his accounts for that year and then he died
phoenix called the police and ran to the accounting place and saw everyone was dead, so he and gumshoe said they would solve this crime for the souls of the victims and familys and friends
gumshoe told phoenix the door was locked and there was no way open but phoenix found an open window but they were on the 50th floor. the murder weapon was a knife and it had lots of fingerprints
"if there was no way to get in the killer must have been already in there" said phoenix but gumshoe told him there was only dead people in there when they got out and if the killer was there hed either be in there or dead on the ground so phoenix concluded that the killer was everyone there except the people alive and it was a suicide thing but why? phoenix suggested radical-6 but gumshoe said there were no traces of radical-6 in the room suddenly one of the police guys killed himself but he didnt have radical-6 so his motive was probably something complex
phoenix then got thinking about complex motives when he realized the motive was obvious they were accountants so they were bored to death so they died
he was wright
the end
