Here's a breakdown:
1. Initial Case: Gilda is hired to investigate a missing student named David. She soon discovers he was involved with a group called "The Dead Drop," who were obsessed with a secret society from the past.
2. New Mystery Emerges: While investigating, Gilda stumbles upon an ancient book, "The Book of Thoth," which seems to be connected to David's disappearance and the Dead Drop group.
3. The Book's Secret: The book contains cryptic clues and mentions a powerful entity that is linked to the secret society. This sparks a new and potentially dangerous mystery for Gilda to unravel.
4. No Straightforward Solution: The case isn't solved in a traditional sense. Instead, Gilda encounters many dangerous individuals, faces her own fears, and learns more about the hidden secrets within the world.
5. Unresolved Threads: "Dead Drop" doesn't tie up all the loose ends. The fate of David remains unknown, and the secrets of "The Book of Thoth" continue to intrigue Gilda, setting the stage for future adventures.
So, while Gilda doesn't definitively solve the initial case in "Dead Drop," she uncovers a much larger mystery, one that will continue to drive her investigations in the subsequent books.
