This is a companion piece set in the same world as earlier works by Dias, bringing back the intriguing protagonist of Four Sittings In A Sinking House. If you haven't read his earlier works, this brief piece may be unsatisfying. There is little backstory or characterization, merely a list of items referring to the previous works, and the choice to keep or abandon each item.
This is a nice treat for fans, and a good reason for newcomers to read his back work.
