This is a word search puzzle without a word list (which makes it a bit more difficult, but not impossible).
The word list is alphabetical with the first word placed in the top left spaces going DOWN each column, meaning the second word in the alphabetical list will go in the spaces directly below the top left word.
There are quite a few "B" and "C" words to find... 11 in total, actually.
Of note, 11 letters are NOT used in the grid (which makes up the final keyword).
The first word is "BARS"
The last word is "WHIP". The next hint contains a complete list of words to find.
Here is the complete list of words to find: Bars, Blood, Boiling Oil, Bonds, Bones, Cage, Cauldron, Cells, Chains, Cobweb, Confessor, Hood, Iron Maiden, Irons, Jailer, Key, Knives, Lash, Manacles, Noose, Prisoners, Rack, Rats, Ropes, Shackles, Thumbscrews, Torch, Warden, Whip.
The keyword is found in the next block of text. If you do not wish to be spoiled, please do not continue.
The 11 letters which were not used spell out the keyword "Executioner".
