Welcome to Frank and FELIX’s third case! If you’re a regular reader, thanks for sticking with us. We think you’ll enjoy what’s coming up in this story. If you’re just joining us, you can get caught up with the “Case Files” dropdown menu directly to your right, or you can just start at the beginning. (We realize the archive system isn’t great; we’re working on that.) We update with new strips every Monday, Wednesday and Friday, and the Police Blotter feature runs on Thursdays.

Wednesday: Who–or what–is TATM?
