The world of Red Dead Redemption 2 is full of intriguing mysteries and hidden details that may fly under the radar for those who are just casually playing through the game. Gamers that want to dive into the open world western in-depth will find all sorts of subtle storylines that aren't official side quests or missions, including the ongoing mystery of the woman in the window at the Emerald Ranch, though some think that they've figured it out.

Players that wish to solve the Emerald Ranch mystery for themselves will want to travel to an abandoned US mail carrier wagon that's located southwest of Fort Wallace in the Cumberland Forest. The exact location is marked here on the map:

Players can loot the mail carriage to find a letter addressed to Miriam Wegner that describes how she lost her significant other Joshua "in such a horrible way." Annabelle, the author of the letter and Miriam's cousin, has apparently written Miriam six times with no response. In the letter, she surmises that Miriam is not responding due to grief and isolation, or that Miriam's father, Annabelle's Uncle Eugene, is withholding the letters from her.

Some players may be wondering what exactly happened to Joshua, and for more information on that, they need to visit the abandoned saloon near the Emerald Ranch. Inside players will find a crime scene, with blood on the floor and bullet holes in the wall. Behind the saloon, players will find the tombstone for Joshua Burgess.

Now if players head to the house at the Emerald Ranch, they will often find Eugene Wegner sitting on the porch. Eugene is hostile, and will almost always challenge players to a fight. Players can safely beat him up without getting in trouble with the law or the locals, presumably because people kind of know that Eugene likely killed Joshua and is now holding Miriam in the house against her will.

Here is a video that explains the Emerald Ranch mystery, though be warned that it does have MAJOR SPOILERS for Red Dead Redemption 2's ending and epilogue:
