In this guide, we’re going to help you collect the clues and solve The Mystery of The Twice-Dead Professor.

If you don’t choose the correct person to accuse the first time, you’ll get less money and XP. If you get it right the first time, you’ll receive:

Step #1: Byng’s Home

Explore the three-storied house, collect all the clues and talk to the relatives and hired help.

  • (TF) The crate next to the bookshelf.
  • (TF) The legal letter on the table.

  • Angela – The maid. She’s the one that found the body.

Step #2: University

The professor’s place of work is full of clues about his work and potential cause of death. There’s a couple of coworkers to talk to as well, not to mention his son’s wife-to-be.

  • Dr. Wilson – The university’s foremost expert on spiders.
  • Virginia – An assistant who was also supposed to become the deceased’s daughter-in-law.

Step #3: Cemetery

This is where the body was burried before it mysteriously reappeared. There’s only one person to talk to and a couple of clues.

Step #4: Abandoned House

The house in the neighborhood where the murder happened and it’s littered with evidence.

Accuse the murderer

After you’ve got the option to accuse, you can go straight to Professor Silas. He’s the one who did it, hoping it would help him become the very best, like no one ever was.
