How to leave mortuary

You leave by way of a secret exit. You will need to talk to a something that isnt what it seems about how to get out. Hint look for a funny worker.

On the upper floor, on the lower left of the map, next to the locked round room is a container on which you can find the key you need.
(I guess this is what you meant.)
