Hints

Doctor's Memo

You received an item in Episode 2 that will help you reveal the secret in this document.
There is a recurring color in the two previous doctor's memos that indicates the location of a hidden message.

The door rubbing can be translated using the same method you used for the tree rubbing in Episode 1.

The order of events in the fable Journey to the Mountaintop will help you complete the shadow vista.

In her letter, Grace tells you how to use the shadow vista. She also says she has imbued the twine with a specific scent, which is a hint for you to access important information in this episode.

On one of the scanned diary pages, Isabella wrote out a phrase from The Blue House passage, which you received in Episode 2. This is a key phrase that can be used elsewhere.
The key phrase can be used on one of the password-protected posts on www.kaylabellamagic.com. Somewhere in the password-protected post, there are two keywords that link to a hidden page. There is an encoded message on the hidden page.

Arrange the pieces on the mountain in the correct order, then use the completed shadow vista in conjunction with another item from this episode to reveal a hidden image.

Use the prism you received in Episode 2. There is a section of the doctor's memo where blue and yellow overlap to form a green triangle. Place the triangle end of the prism on the green triangle to reveal two hidden messages.
If you look through the prism at the correct angle, two hidden messages can be seen in the reflections on either side of the prism:
- "I need the life of Grace"
- "I want to hurt myself"

The correct order to arrange the shadow vista pieces, from the bottom of the mountain to the top, is: the bird with the pale beak, the animal with the bushy tail, the dark bird, and the oak tree branch.

Grace says that the twine is imbued with the scent of rosemary. "Rosemary" is the title of the password-protected post on www.kaylabellamagic.com to access in this episode.

In the password-protected post, the linked words "running" and "key" hint that the encoded message on the hidden page is a running key cipher. To decode the running key cipher, use the key phrase that Isabella wrote on the scanned diary pages: "The moon was a big white hole in the sky."
To solve the running key cipher, consult a standard tabula recta. The top row represents the letters of the key phrase and the leftmost column represents the decoded letters.
Find the first letter of the key phrase, which is "T", on the top row of the tabula recta. Move down the "T" column until you find the first letter of the encoded message, "A". Then, move left across the row to the leftmost column to find the corresponding letter, which is the first letter of the decoded message - "H". Repeat these steps for each letter of the cipher.
The decoded message is: "HELP HE KNOWS IM HERE FIND MY TRUE NAME"

When the pieces of the shadow vista are correctly aligned, light the black candle and hold it near the bottom point of the mountain. The light from the flame will cast a shadow in the shape of a deer.
The password for the relevant password-protected post on www.kaylabellamagic.com is "deer".
