Cryptic crossword No 4,133

Special Instructions: There's a minor theme to this one but it didn't start out that way: it was only when the final bit of gridfill offered two intersecting solutions in the NE that I looked over the rest and went "wait a minute..."

Type to enter letters. Use the arrow keys to move between cells, Tab and Shift+Tab to move between clues, and Escape to leave the grid.
