As a detective, my first instinct was to consider various meanings of the word ‘board‘. It could potentially refer to a game board or a whiteboard where items are put up. I then considered the phrase ‘Put on‘ which could refer to positioning or mounting something. Putting these clues together, I focused on words that relate to positioning items on a board, such as ‘install‘ or ‘place‘. However, none of these options fit the structure of the crossword puzzle. Then I realized that the word ‘board‘ could also refer to a bulletin board or a notice board where announcements are made. This led me to think of words that could be used in this context, and the word ‘POST‘ immediately came to mind. It had the correct number of letters and fit perfectly in the crossword puzzle. Using logic and deduction, I had figured out that the answer to the crossword clue ‘Put on the board‘ was ‘POST‘, which was a great accomplishment as a detective.
