"You dumped it into the chest," said Peter.

"Yes. I had a horrible shock the other morning when I found you looking in."

"Nothing like the shock I had when I found the silver sand there."

"Silver sand?"

"Out of the conservatory."

"Good gracious!" said Mary.

"Well go on. You knocked up Freddy and the Pettigrew-Robinsons. Then you had to bolt into your room to destroy your farewell letter and take your clothes off."

"Yes. I'm afraid I didn't do that very naturally. But I couldn't expect anybody to believe that I went burglar-hunting in a complete set of silk undies and a carefully knotted tie with a gold safety-pin."

"No. I see your difficulty."

"It turned out quite well, too, because they were all quite ready to believe that I wanted to escape from Mrs. Pettigrew-Robinson-except Mrs. P. herself, of course."

"Yes; even Parker swallowed that, didn't you, old man?"

"Oh, quite, quite so," said Parker gloomily.

"I made a dreadful mistake about that shot," resumed Lady Mary. "You see, I explained it all so elaborately-and then I found that nobody had heard a shot at all. And afterwards they discovered that it had all happened in the shrubbery-and the time wasn't right, either. Then at the inquest I had to stick to my story-and it got to look worse and worse-and then they put the blame on Gerald. In my wildest moments I'd never thought of that. Of course, I see now how my wretched evidence helped."

"Hence the ipecacuanha," said Peter.

"I'd got into such a frightful tangle," said poor Lady Mary, "I thought I had better shut up altogether for fear of making things still worse."

"And did you still think Goyles had done it?"

"I-I didn't know what to think," said the girl. "I don't now. Peter, who else could have done it?"

"Honestly, old thing," said his lordship, "if he didn't do it, I don't know who did."

"He ran away, you see," said Lady Mary.

"He seems rather good at shootin' and runnin' away," said Peter grimly.

"If he hadn't done that to you," said Mary slowly, "I'd never have told you. I'd have died first. But of course, with his revolutionary doctrines-and when you think of Red Russia and all the blood spilt in riots and insurrections and things-I suppose it does teach a contempt for human life."

"My dear," said the Duchess, "it seems to me that Mr. Goyles shows no especial contempt for his own life. You must try to look at the thing fairly. Shooting people and running away is not very heroic-according to our standards."

"The thing I don't understand," struck in Wimsey hurriedly, "is how Gerald's revolver got into the shrubbery."

"The thing I should like to know about," said the Duchess, "is, was Denis really a card-sharper?"

"The thing I should like to know about," said Parker, "is the green-eyed cat."

"Denis never gave me a cat," said Mary. "That was a farradiddle."

"Were you ever in a jeweller's with him in the Rue de la Paix?"

"Oh, yes; heaps of times. And he gave me a diamond and tortoiseshell comb. But never a cat."

"Then we may disregard the whole of last night's elaborate confession," said Lord Peter, looking through Parker's notes, with a smile. "It's really not bad, Polly, not bad at all. You've a talent for romantic fiction. I mean it! Just here and there you need more attention to detail. For instance, you couldn't have dragged that badly wounded man all up the path to the house without getting blood all over your coat, you know. By the way, did Goyles know Cathcart at all?"

"Not to my knowledge."

"Because Parker and I had an alternative theory, which would clear Goyles from the worst part of the charge, anyhow. Tell her, old man; it was your idea."

Thus urged, Parker outlined the blackmail and suicide theory.

"That sounds plausible," said Mary-"academically speaking, I mean; but it isn't a bit like George-I mean, blackmail is so beastly, isn't it?"

"Well," said Peter, "I think the best thing is to go and see Goyles. Whatever the key to Wednesday night's riddle is, he holds it. Parker, old man, we're nearing the end of the chase."

CHAPTER X

Mr. Goyles was interviewed the next day at the police-station. Mr. Murbles was present, and Mary insisted on coming. The young man began by blustering a little, but the solicitor's dry manner made its impression.

"Lord Peter Wimsey identifies you," said Mr. Murbles, "as the man who made a murderous attack upon him last night. With remarkable generosity, he has forborne to press the charge. Now we know further that you were present at Riddlesdale Lodge on the night when Captain Cathcart was shot. You will no doubt be called as a witness in the case. But you would greatly assist justice by making a statement to us now. This is a purely friendly and private interview, Mr. Goyles, as you see, no representative of the police is present. We simply ask for your help. I ought, however, to warn you that, whereas it is, of course, fully competent to you to refuse to answer any of our questions, a refusal might lay you open to the gravest imputations."

"In fact," said Goyles, "it's a threat. If I don't tell you, you'll have me arrested on suspicion of murder."

"Dear me, no, Mr. Goyles," returned the solicitor. "We should merely place what information we hold in the hands of the police, who would then act as they thought fit. God bless my soul, no-anything like a threat would be highly irregular. In the matter of the assault upon Lord Peter, his lordship will, of course, use his own discretion."

"Well," said Goyles sullenly, "it's a threat, call it what you like. However, I don't mind speaking-especially as you'll be jolly well disappointed. I suppose you gave me away, Mary."

Mary flushed indignantly.

"My sister has been extraordinarily loyal to you, Mr. Goyles," said Lord Peter. "I may tell you, indeed, that she put herself into a position of grave personal inconvenience-not to say danger-on your behalf. You were traced to London in consequence of your having left unequivocal traces in your exceedingly hasty retreat. When my sister accidentally opened a telegram addressed to me at Riddlesdale by my family name she hurried immediately to town, to shield you if she could, at any cost to herself. Fortunately I had already received a duplicate wire at my flat. Even then I was not certain of your identity when I accidentally ran across you at the Soviet Club: Your own energetic efforts, however, to avoid an interview gave me complete certainty, together with an excellent excuse for detaining you. In fact, I'm uncommonly obliged to you for your assistance."

Mr. Goyles looked resentful.

"I don't know how you could think, George-" said Mary.

"Never mind what I think," said the young man roughly. "I gather you've told 'em all about it now anyhow. Well, I'll tell you my story as shortly as I can, and you'll see I know damn-all about it. If you don't believe me I can't help it. I came along at about a quarter to three, and parked the 'bus in the lane."

"Where were you at 11.50?"

"On the road from Northallerton. My meeting didn't finish till 10.45. I can bring a hundred witnesses to prove it."
