The forum won't let me update the walkthrough, but here it is for now.
15. Sophie finds herself lost in an uber creepy asylum!
Link to the Asylum!a. When you get inside the asylum, click on the lamp that is becoming unhinged from the ground... you'll need it later.
b. Next, find what appears to be a dining room full of zombies. Fight them off (by clicking on them!). After they leave the room, get a key from the janitor's pocket and a journal page from off the floor.
c. Next, find a room with a doctor and a locked cabinet. Click both of the doctor's pocket. One contains a key while the other contains another journal page. Unlock the cabinet by clicking on the lock and take the shovel with you.
d. Go back into the hallway and find the courtyard. There you will find a pile of leaves. Click on it, and Gilly will uncover a bone. Once the bone is uncovered, click on the bone again to put it into your inventory.
e. Finally, find the room with a jail cell and a zomutt. Distract the zomutt by clicking on it and giving it the bone. Go into the jail cell, find your last journal page under one of the cell doors and open the cell your key unlocks!
To be continued again....
I think you need to find the zomutt first and read the page you find there before you can dig and find the bone. Zomutt can be found through the far right door, than one of the six doors in that corridor (some use far right, i used the far left)
