a quarter to six on
Wednesday
I propose that you , in your uniform , shall be seated there with me to receive him , and I am anxious to study Mr. Macpherson 's countenance when he realises he has walked in to confront a policeman . If you will then allow me to cross-examine him for a few moments , not after the manner of Scotland Yard , with a warning lest he incriminate himself , but in the free and easy fashion we adopt in Paris , I shall afterwards turn the case over to you to be dealt with at your discretion . ' ` You have a wonderful flow of language , Monsieur Valmont , ' was the officer 's tribute to me . ` I shall be on hand at a quarter to six on Wednesday . ' ` Meanwhile , ' said I , ` kindly say nothing of this to anyone . We must arrange a complete surprise for Macpherson . That is essential .
