I am a bit stuck. I have got for 21 across BROKER as the answer to: generic name for a person who buys and sells stocks, shares, bonds, currency; or another name for a merchant ship. The K clashes with answer to 6 down which I have as ROSE MADDER as the answer to: Pinkish pigment derived from the roots of a plant of the same name used in the works of J.M.W. Turner.
One of the answers must be wrong, but which? Could someone help me please? Thanks
