Madam, - Luke Cahill (September 2nd) wonders if my comments on Opus Dei were informed by acquaintance with the Da Vinci Code, and goes on to accuse me of shallow thinking. It may disappoint him to learn that since I have neither read that book nor seen the film, my measured and well-founded opinions about the organisation are founded on considerably surer grounds. - Yours, etc,
HUGO BRADY BROWN,
Stratford on Slaney,
