To complete your collection of trinkets in Thief, you not only need to find the ones hidden throughout the campaign chapters but also the 27 that are scattered throughout the city hub. To be able to access all of these places, you will need to accept all the jobs from Basso--you don’t need to complete them, just accept all of them at once and you'll have access to every place these items are found in. Otherwise, windows will be boarded up and inaccessible etc.
For the rest of the items see our Campaign Collectibles Guide, and to retry missions check out our Chapter Replay Locations Guide.
