One-Way Trip

From: Kira Woodville
Description: I’ve taken a taxi several times, but nothing happened to me. That means people aren’t randomly disappearing. There’s an agenda at work. Here are the things left behind by the missing passenger. Any thoughts? What do you think, for instance, about this umbrella?
Completed: Yes, an entirely normal collection except for a lady’s umbrella... It was a male passenger, after all. I have no idea why he was carrying it.
