"You misunderstood what Mrs. Carter meant," said Mary. "Our guest is a Prince, and unfortunately my cousin's spaniel's called Prince. It was just that my cousin felt that it might be a little awkward." She saw a look of bewilderment on the Inspector's face, and added desperately: "On account of them both answering to the same name, I mean."

Hugh gripped his underlip between his teeth, and gazed rigidly at the opposite wall.

The Inspector was obviously shaken. He stared very hard at Mary, and said severely: "I'm bound to say, it doesn't make sense to me, miss."

"No. No, it was very silly and trivial. I told you it had no bearing on the case."

The Inspector turned back to Ermyntrude. "This Prince, madam, is a friend of yours, I take it?"

"Well, of course he is!" replied Ermyntrude. "He's a very dear friend of mine!"

"I should like to see him, if you please," said the Inspector, feeling that he was nearing the centre of the labyrinth at last.

"You can't see him; he's gone out to tea with Dr Chester. Besides, what's the use of your seeing him? You don't suppose he killed my husband, do you?"

"I don't suppose anything, madam," said the Inspector stiffly. "But it's my duty to interrogate everyone staying in this house. If he's out, I'll wait for him to come back; and in the meantime I wish to ask Miss Fanshawe a few questions."

"Don't you think you're going to drag my girl into this!" said Ermyntrude, a dangerous gleam in her eyes. "I'll put up with a good deal, but I won't put up with that! My Vicky's an innocent child, just on the threshold of life, and if you imagine I'm going to stand by while you rub the bloom off her, you'll very soon find out where you get off, and so I warn you!"
