Thanks, Rollo. I will have to put in some serious thinking on your answers to both questions.
Christiana: these Inquisitor puzzles usually have an extra wrinkle in that we have to add or remove letters from the clues or the answers. The clue alone would not help you and explaining the whole thing would take up too much space.
I have finally figured out the rocket, thanks for that, but no further pennies seem willing to drop. I take it this is a series with two main characters? UK? And how "old" is "old"?
