“For two reasons,” replied Wise, seriously. “First, any one criminally implicated might wish it to remain unknown; second, any one wishing to shield another, might also wish no discoveries made.”

“But you don’t think any of us are criminally implicated, I hope,” and Braye looked questioning.

“There are others in this house beside you people,” Wise returned; “and I tell you frankly, I’m not ready yet to suspect any one or even imagine who the criminal may be. I only state positively that disembodied spirits are not responsible for those two tragic deaths. Also, may I ask you to remember, that I’ve only just arrived, that I’ve had a tiresome journey, that I’d like rest and refreshment, and that there are more days coming for my further work.”

“Why, bless my soul!” exclaimed the Professor, “that’s all true! Do you know, Mr. Wise, it seems as if you’d always been here, it seems as if you were already one of us.”

“Thank you, sir, that’s a pleasant compliment to my personality, anyway. And now, if you please, Mrs. Landon, may I be shown to my room?”

“Certainly,” said Milly, and she rang for Thorpe, as Landon rose to escort the guest himself.

“Where’s that girl?” said Norma, looking round after the detective had gone off, “what became of her?”

But there was no sight of the little black-robed figure.

“Oh, let her alone,” said Eve, “she slid out to the kitchen, I think. Hester will look after her. That man said to pay no more attention to her than to his hand luggage. She’ll look out for herself, I’ve no doubt. Isn’t she awful, anyway?”

“I think she’s pretty,” said Norma, “in a weird, elfin sort of way.”
