As a detective solving the mystery of the crossword clue ‘Old Testament prophet’, my thought process first began by analyzing the number of letters in the answer. With four spaces, I knew the prophet’s name must be short. I started to recall all the prophets I knew from the Old Testament, and that’s when the name Amos came to mind. I remembered that Amos was known for his prophecies about social injustice and he lived during the 8th century BC. To confirm my hunch, I checked the surrounding clues in the crossword puzzle and saw that the one adjacent to ‘Old Testament prophet’ was ‘Capital city of Greece’. I knew Greece’s capital is Athens, so I started to put the letters A-T-H-E-N-S in the spaces. That’s when I realized that the fourth letter of ‘Athens’ was the letter ‘E’, which also appeared in the name ‘Amos’. Trusting my intuition, I wrote ‘AMOS‘ in the spaces for ‘Old Testament prophet’, and it was a perfect fit. With a smile, I had found the solution to the crossword clue, another case solved!
