[SPOILERS] Conservatory Help

[Lestrad]

Just out of curiosity, I feel I've searched the entire interior of the building, including the basement archives, janitor's closet, etc, but I can't find the security office to get the key to access the prototype.

I know I could just break down the door or (probably) smash the glass, but I like to challenge myself more by actually looking for the keys.

[VideoJones]

Is there not some kind of window above the door or something or rat hole? Not sure where the keys are as I've only gotten in there via other means.

[Certified Lawyer Boy]

the key is inside, only way in without breaking the glass is through a window directly above the door to the security room.

[Dream Chaser]

If memory serves right, I think I found the key inside the room, next to a dead guard.

[Random Person]

use blink to get through the space above the door, break the door with your sword, shoot it open with teh gun or make it explode with a grenade

I see now, the "Constable sign" was hidden behind a display case. The room with the prototype *was* the security room. -_-
