They didn’t see clearly, but they were more than ready to promise whatever this girl asked, and then between the two, Zizi was served with such a luncheon as might have befitted a royal guest.

“Goodness, gracious, sakes alive!” she exclaimed, “don’t bring me anything more, I beg of you. I shall go to sleep like an anaconda and not wake up for six months!”

Then, while the detective ate his luncheon at the table with Minna Varian and her secretary, Zizi went in search of the nurse.

She found Mrs Fletcher eating her meal from a tray in her sitting room. It hurt her pride to do this, but Minna Varian declared that she saw quite enough of Fletcher between meals and must have some respite.

“Nice to eat alone, I think,” was Zizi’s observation as she entered, uninvited, and perched herself on the arm of a nearby chair.

“You’re Fletcher, aren’t you? Now, won’t you please tell me some things confidentially? I see, you’re a woman of deep perceptions, and are not to be caught napping. Tell me, do you think Mrs Varian went down stairs a second time last night?”

“That she did not,” asserted the nurse. She was flattered at Zizi’s attitude and would have told her anything she asked.

“How do you know?”

“I can’t go to sleep myself, you see, till Mrs Varian is asleep. So I always wait until I hear her steady breathing before I let myself drop off.”

The statement was too surely true to be disbelieved and Zizi went on.
