Have noticed lots of clues for this quiz for which I am very thankful.
There are however 3 that I seem to be the only one who has not solved them.
4. Sole highwayman (7)
44. Reserved nothing, the heartless exploiter of illegal immigrants (6)
48. Frenchman without right grade left the party (8)
I would be grateful for any additional clues, however vague, you could give me.
