Hints
LFoA Internal Memo
- Use the magnifying glass to identify a hidden code in this document.
- There is tiny text hidden throughout the document, which can be read with the magnifying glass.
- The text reads: "ALICE 3⌃7 mod 17", "BOB 3⌃15 mod 17", and "FOOTNOTE: HvwgkwzzbchvoddsbouowbBwq".
- The mention of "Alice and Bob" will help determine the method to understanding how LFoA exchanges key information.
- The Diffie-Hellman key exchange involves two parties performing a series of public equations to arrive at a shared secret number.
- Alice and Bob are the standard names of the two parties involved in the Diffie-Hellman key exchange. Alice's equation can be represented as NA (mod P), and Bob's equation can be represented as NB (mod P).
- Alice's public key is 3⌃7 (mod 17), which is equal to 11. Bob's public key is 3⌃15 (mod 17), which is equal to 6. Therefore, N = 3 and P = 17.
- Alice swaps N in her equation for the solution to Bob's, and Bob swaps N in his equation for the solution to Alice's.
- 1115 (mod 17) = 14, and 67 (mod 17) = 14.
- The shared number between them is 14.
Small Note
- Compare the note to any existing handwriting samples to determine the author.
Reveals
LFoA Internal Memo

Solution
Suspect Elimination
Antonio Villar
Means
- Antonio had access to diazepam through his drug-selling business with Charlie. Based on the toxicology report from Episode 3, diazepam was found in Charlie's system when he died.
Motive
-
Antonio worked closely with Charlie in their shared drug-selling business, which had originated in high school. They had a conflict over this business in later years. These facts are confirmed by:
- Yearbook (Episode 1): The hidden blacklight message in Episode 1 is Antonio's handwriting and mentions a "biz".
- Socks (Episode 3): The hidden blacklight message on the paper inside the socks reveals that Charlie and Antonio had a "delivery system" in the past.
- Bank Statements (Episode 3): The hidden messages in the check memos reveal that Antonio and Charlie had a conflict over the drug-selling business.
Opportunity
-
Antonio could not have been at the murder scene at the time of Charlie's death (approximately 9:37 PM) because he was at Dimitri's Taverna at 9:32 PM. In his statement in Episode 1, Antonio says he arrived at the Taverna before anyone else in the group. These facts are confirmed by:
- Surveillance Photo on DeviantTracker: Corroborates that Antonio was the first to arrive at the Taverna. The photo that shows Antonio outside the Taverna is time-stamped at 9:32 PM, and he could not have made it to the murder scene in 5 minutes or less to kill Charlie.
- Suspect Photo of Antonio (Episode 2): Corroborates that the man in the 9:32 PM surveillance photo is indeed Antonio because the hair and facial features match with the photo given in Episode 2.
Susan Li
Means
- As a veterinarian, Susan had access to the drug that incapacitated Charlie the night of his murder, and was known to have used it recently. Her last known use of diazepam led to a death, though her lawsuit alleges it was through no fault of her own.
Motive
-
Susan's career and reputation were at risk by Charlie's negligence at the pharmacy. She was seeking $150,000 in damages in a lawsuit against Main Street Pharmacy for Charlie's actions. These facts are confirmed by:
- Newspaper Article (Episode 2): Proves that Susan's reputation was at stake for the death of a prize racing horse, and that she laid at least some of the blame on Charlie and Main Street Pharmacy.
- Email Chain (Episode 2): Shows that there was a documented history of negligence on Charlie's part that affected Susan's work. This is where Susan first threatened legal action.
- Legal Complaint (Episode 2): Susan's filing of charges against Main Street Pharmacy for endangering her business and reputation.
Opportunity
-
Susan claimed she was not at the scene of the crime on the night of the murder in her witness statement to Michelle. Based on her proven location at her veterinary office before Charlie was seen to have left the reunion, she could not have been the person to have left with him and then murdered him. These facts are confirmed by:
- Aura's Witness Statement (Episode 1): Corroborates Susan's location and her claim that she made a call to Aura around the time of 9:45 PM from the veterinary office phone.
- Phone Records: Confirms that there was a call made from a landline in Susan's veterinary clinic to a lawyer's office the night of the murder at 9:11 PM, as she claimed in her witness statement. She would not have had time to speak on that phone for 32 minutes and then drive to The Grove to murder Charlie.
