Mr Bray wrote cryptic puzzles about a school's senior management team that can be solved by linking clues to a single number. The clues reference a restaurant owned by "Burns", Mr. Bray thinking he is half his real age, the number of rugby players and the fullback having in common, Mrs. Mackie shouting a number when winning her first point in a sport, and the "magic constant" of a square puzzle that Mr. Fruish likes the song "Dead Man's Chest" from while watching Pirates of the Caribbean to calm down during a stressful kitchen renovation. Filling in box 18 on a number grid with the solved number is requested.
