Note: Spoilers will be ahead:

The snake or the flower, which poison “killed” him first? Or was it a weird combo of both hmm…

Puzzles and more snakes o my. I am still lost as of right now however it is interesting to me :).

A board with nails  laced with ground up oleander powder to look like a snake bite “killed” him as the “murder weapon” very low-tech however ingenious non the less.

I still have no clue who the “Killer” is dear reader, I am definitely going to keep watching to find out :).
