who murdered sally last night?

Last night sally celebrated her birthday among friends, business partners, and her best clients. All glamour and love in a cottage down in the forest. In the morning, sally was found dead in the…

“Tell us , WHERE?” Somebody yelled in all-caps in the group chat.

she ran away?

nobody slept. police say sally died between 3:11 and 3:34am. weird thing? every guest's phone was active except one. someone's lying about being asleep.

i found a photo from the party. zoom into the mirror behind sally. there's someone standing in the hallway. nobody remembers them being there.

sally scheduled an email for 8am. it was sent after she died. subject line: "if you're reading this, they found me."

everyone keeps talking about enemies. what about friends? the guest list was private. whoever killed her knew exactly who would be in that cottage.

police released the seating chart. one chair was moved after midnight. only one person switched places with sally during cake.

deleted messages recovered. at 2:47am sally texted someone: "i know what you did." no reply. ten minutes later her phone goes silent.

new evidence. security camera at the gas station caught a guest buying bleach and gloves before the party. guess whose receipt was in the trash?

i just noticed something. everyone posted birthday photos. one person uploaded theirs at 4:02am. before the body was discovered. how did they know the night was over?

SYSTEM NOTE: an anonymous account has joined the chat. username: @sally_lastseen. first message: "you're accusing the wrong person."

sally wasn't murdered for money, revenge, or jealousy. she died because she discovered what happened three years ago at the lake. and the killer is reading this chat right now.
