The Threshold Bureau's formal documentation practice requires that every significant finding be recorded in two parts: what was achieved, and what the achievement cost. What was discovered. What the discovery asked of the person who made it.

This practice did not originate as a safety protocol. It originated as honesty.

The researchers documented here did not die because they were careless. They died because they were thorough.

The names of the deceased are real, used with permission of their families, who were told a version of the truth and who, in every case, deserved the complete version.

The complete version is this.

A note on the timestamp that recurs throughout this record: 14:23:00 is the exact moment — to the second — at which Dr. Yara Osman's dive camera recorded the stillness that preceded her death. It is also the time at which the Bureau's founding memo was signed, a coincidence that the Bureau's lead analyst spent three weeks trying to verify as meaningful before concluding it was not.

He was wrong about that.

This is also part of the record.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
