He waited to make his effect--Sir Arthur is a born actor--and there is no doubt that he made it, when in his slowest, most drawly tones he said quietly; "'With regard to this alleged murder of one William Kershaw, on Wednesday, December the 10th, between 6.15 and 8.45 p.m., your Honour, I now propose to call two witnesses, who saw this same William Kershaw alive on Tuesday afternoon, December the 16th, that is to say, six days after the supposed murder.' "It was as if a bombshell had exploded in the court.

Even his Honour was aghast, and I am sure the lady next to me only recovered from the shock of the surprise in order to wonder whether she need put off her dinner party after all.
"As for me," added the man in the corner, with that strange mixture of nervousness and self-complacency which had set Miss Polly Burton wondering, "well, you see, _I_ had made up my mind long ago where the hitch lay in this particular case, and I was not so surprised as some of the others.
"Perhaps you remember the wonderful development of the case, which so completely mystified the police--and in fact everybody except myself.
Torriani and a waiter at his hotel in the Commercial Road both deposed that at about 3.30 p.m.on December the 10th a shabbily dressed individual lolled into the coffee-room and ordered some tea.

He was pleasant enough and talkative, told the waiter that his name was William Kershaw, that very soon all London would be talking about him, as he was about, through an unexpected stroke of good fortune, to become a very rich man, and so on, and so on, nonsense without end.
"When he had finished his tea he lolled out again, but no sooner had he disappeared down a turning of the road than the waiter discovered an old umbrella, left behind accidentally by the shabby, talkative individual.
As is the custom in his highly respectable restaurant, Signor Torriani put the umbrella carefully away in his office, on the chance of his customer calling to claim it when he had discovered his loss.

And sure enough nearly a week later, on Tuesday, the 16th, at about 1 p.m., the same shabbily dressed individual called and asked for his umbrella.

He had some lunch, and chatted once again to the waiter.
