The quest points strongly toward Reverend Nathaniel Pastodi, but the investigation has an important second lead. If you rush the confrontation, the game can finish without revealing the actual culprit. Ask questions first to uncover the clue involving formaldehyde.

● Quick Answer

At Crippled Kate’s, choose “Got a few questions for you first” and then ask about the formaldehyde clue. The conversation redirects the investigation toward coroner Hubert Rejk and unlocks the follow-up warehouse encounter.
