In the Treasure Map (related to Thompson Chain), there is text like this "Hunt For Your Answers In The Treasure ChestM". Shouldn't that be a link to the accompanying or related "Treasure Chest" by the same authors as "Treasure Map"?
Here are the citations, which make them seem related to the TCR set :
