"Murder Most Foul" is the twelfth episode of Season Six of ABC's Once Upon a Time. It was written by Jerome Schwartz & Jane Espenson, and directed by Morgan Beggs. It is the one hundred and twenty-third episode of the series overall, and premiered on March 12, 2017.
Before Hook takes the next step in his relationship with Emma, he wants to make sure David sees him as more than just a pirate. So when David asks Hook to help him uncover the truth about his father’s death, Hook agrees. Meanwhile, Regina works to acclimate Robin to life in Storybrooke, but soon discovers he has a dark side that makes the task much more complicated than she anticipated.
Originally, donkeys wearing hats were set to appear in the episode, a reference to The Adventures of Pinocchio, in which all boys sent to Toyland are turned into donkeys. The donkeys were brought in for the episode, dressed up in headgear and everything and filmed in an enclosure in front of a green-screen, but this ended up being cut from the episode.

- Two illustrations by the eighteenth century German botanist Johann Wilhelm Weinmann are hanging on the wall in Regina's dining room. The first one is Apocynum seu Fritillaria crassa monstrosa and is from the first volume of Weinmann's florilegium Phytanthoza iconographia, published in eight volumes between 1737 and 1745. Fritillaria crassa is an old name for the plant Orbea variegata, a type of carrion flower. The other one is an illustration of a group of cocklebur plants, from volume 4 of Phytanthoza iconographia.
- Apocynum seu Fritillaria crassa monstrosa can also be seen in Regina's hallway in the Season One premiere "Pilot" and in Regina's kitchen in the Season One episode "An Apple Red as Blood".
- The illustration of the cocklebur plants could also be seen next to Regina's bedroom window when she woke up in Storybrooke for the first time in the Season Two episode "Welcome to Storybrooke", but it could only be seen from far away and not very clearly.

It was published in five volumes between 1767 and 1776 and was illustrated by Violante Vanni and Lorenzo Lorenzi.
- The same picture appeared in Regina's bedroom when she woke up in Storybrooke for the first time in the Season Two episode "Welcome to Storybrooke".
