Recipient After Death

I am a community courier. Starting last month, I always receive express messages from the deceased. Empty buildings, recipients that have long since been canceled, and packages that are never signed for. The real estate agent said that I was dazzled, my colleagues said that I was in trouble, and the police checked all the surveillance cameras, but they said everything was normal. Until I opened the first Dead Man Express. There was only a note inside: Next, it's you.
