Investigating a mystery can be a very engaging and enjoyable type of quest. You need to move around an area and interact with various objects and NPCs, all leading to one satisfying realization or truth you previously did not know. Sometimes these mysterious are not straight forward and players may need some help in figuring out something that is deliberately meant to stump them.
Assassin’s Creed Mirage features many different investigations throughout the game. This one pertains to the missing Ahmad ibn Musa and will see the player looking for clues of their whereabouts by searching their workshop, discovering the location of an excavation site out in the dessert, and infiltrating the Great Bimaristan to find Doctor Hassan.
Search Ahmad Ibn Musa’s Workshop
During your playthrough of the game, you will need to conduct an investigation to find Ahmad ibn Musa. Once you start this investigation, your first objective will be to head to the House of Wisdom where you will speak with Fazil. You can speak to the NPC near Fazil, and they will tell you that Ahmad’s workshop is located behind him. This will place a quest marker on the door behind the NPC — head over to the quest marker and interact with the door for a cutscene before Basim will enter the workshop.
You can use your Eagle Vision in this room to highlight many of the objects. From the door at the entrance of the workshop, turn left and go forward, you can pull the bookshelf away from the wall to reveal a hidden piece of cloth that serves as a clue. Interact with the other highlighted objects to collect all the clues. Two of them are on the same side as the hidden cloth, while one more lies in the corner opposite the hidden cloth.
Gather Intel At The Excavation Site
Once you have all the clues, you will be able to speak with the attendant, your objective will now be to follow them. Once you and the attendant are alone, you will get some information out of them about where to find the Excavation Site. This site is located south of Wilderness West. While looking at your map, after the river, you will see there is a section that has roads on all sides of it that form a square — the Excavation Site is within this square.
Once you get close enough, you will receive a message on your screen that the location has been discovered. Use Enkidu to survey the area to mark Intel. You will also need to speak with the NPC that is digging at the site. Gather the Intel while avoiding detection by the guards in the area. After you have collected enough Intel at this location, you can head over to the Great Bimaristan.
Assassinate Doctor Hassan At Great Bimaristan
Enter the building from the north side of the map and follow the wall on your right. This will lead you to a note on the wall informing you that the office of Doctor Hassan is just beyond the door next to it. However, this door is locked, and you will need to get some keys from one of the nurses in the area. Backtrack to the entrance and head east through the open door frame. Head south and watch the rooms on the west side as you walk down the path, the second room will have a woman who is one of the nurses.
You will need to pickpocket her to get the keys from her. Now head back to the Doctor Hassan’s Office and unlock the door. Use your Eagle Vision to highlight points of interest in the room and look for clues. Between the entrance you came in from and the other side of the room, you will see a group of NPCs. To the right of them will be a bench you can use to blend in and eavesdrop on their conversation. Head up onto the roof and you will find a locked door.
Turn right, follow the wall around two corners, and keep running to find some stairs to go up. There is a guard stationed in the area, so take your time looking around corners to silently get the drop on him. Once you are at the top of the stairs, head north, and you will find an open window you can pass through. The Doctor is in this room and can be assassinated easily. Once you have killed the doctor and left the area, the case will be closed.
