"Come to think of it, why should you have? Anyhow, I asked Fleming about it, and he said he did remember, now he came to think of it, that on the Thursday morning he'd found the window open, and couldn't account for it. And here's another thing. I've had a letter from my friend Tim Watchett. Here it is:

"My Lord,—About our conversation. I have found a Man who was with the Party in question at the 'Pig and Whistle' on the night of the 13th ult. and he tells me that the Party borrowed his bicycle, and same was found afterwards in the ditch where Party was picked up with the Handlebars bent and wheels buckled.

"Trusting to the Continuance of your esteemed favor.
"Timothy Watchett."

"What do you think of that?"

"Good enough to go on," said Parker. "At least, we are no longer hampered with horrible doubts."

"No. And, though she's my sister, I must say that of all the blithering she-asses Mary is the blitheringest. Taking up with that awful bounder to start with—"

"She was jolly fine about it," said Mr. Parker, getting rather red in the face. "It's just because she's your sister that you can't appreciate what a fine thing she did. How should a big, chivalrous nature like hers see through a man like that? She's so sincere and thorough herself, she judges everyone by the same standard. She wouldn't believe anybody could be so thin and wobbly-minded as Goyles till it was proved to her. And even then she couldn't bring herself to think ill of him till he'd given himself away out of his own mouth. It was wonderful, the way she fought for him. Think what it must have meant to such a splendid, straight-forward woman to—"

"All right, all right," cried Peter, who had been staring at his friend, transfixed with astonishment. "Don't get worked up. I believe you. Spare me. I'm only a brother. All brothers are fools. All lovers are lunatics—Shakespeare says so. Do you want Mary, old man? You surprise me, but I believe brothers always are surprised. Bless you, dear children!"

"Damn it all, Wimsey," said Parker, very angry, "you've no right to talk like that. I only said how greatly I admired your sister—everyone must admire such pluck and staunchness. You needn't be insulting. I know she's Lady Mary Wimsey and damnably rich, and I'm only a common police official with nothing a year and a pension to look forward to, but there's no need to sneer about it."

"I'm not sneering," retorted Peter indignantly. "I can't imagine why anybody should want to marry my sister, but you're a friend of mine and a damn good sort, and you've my good word for what it's worth. Besides—dash it all, man!—to put it on the lowest grounds, do look what it might have been! A Socialist Conchy of neither bowels nor breeding, or a card-sharping dark horse with a mysterious past! Mother and Jerry must have got to the point when they'd welcome a decent, God-fearing plumber, let alone a policeman. Only thing I'm afraid of is that Mary, havin' such beastly bad taste in blokes, won't know how to appreciate a really decent fellow like you, old son."
