Private to Kennet
One dead, another missing. Shadows around the Wishing Tree, customers getting closer to outright violence every day.

Why are we still here, Kennet? Clearly London doesn't agree with us this time of year...

The escapologist got a bit tied up. Apologies to anyone that was inconvenienced by my disappearing act tonight.

We have a problem Would you believe me if I said I had no idea what happened between 3 and 4 this morning?

The Ringmaster wants you to look inside of my head and find some missing memories. When are you free?

Is Halloween some kind of special event or something? I don't understand the purpose of dressing in a costume and picking up candy from strangers.
