A Study in Scarlet by Foxymoron

"What do you make of this traveller?", asked Holmes, arriving at the Baker St Bridge Club, 221b Baker Street.

"Very odd," replied Watson. "It must have been mis-boarded, I presume. EW made slam (6NT, 6H or 6D) at all tables except one in which NS made 7NT and one where 6NT went one off by EW."

"On the contrary, the result was correct." "But did you not notice that EW were Lord Dunsany and his wife Lady Beatrice Child Villiers?"

"Good gracious, how did you deduce that?", responded Watson.

"Elementary," responded Holmes, "Lady Villiers has a bad habit of showing her hand to her partner before the opening lead. Also the writing of 7NT= is of one who is an expert in Calligraphy, and a writer of some 90 books would have that skill. And he always scores, whichever seat he is in. They clearly reached 6NT by East and West showed her hand to her partner before the final pass."

Holmes continued: "Now South, a chap called Charlie, bid 7NT and was entitled to treat every West card as a major penalty card. It is a simple matter now, Watson, for you to construct the whole deal. 7NT cannot be beaten even by best defence. And East does not have any penalty cards."

So, over to you. Solution after Xmas.
