“At the end of this time, my lord, I felt bound to conclude either that the lady had been taken ill or that something untoward had occurred. I summoned a female attendant who happened to cross the hall and informed her that I had been entrusted with a message for a lady whose dress I described. I begged her to ascertain from the attendant in the Ladies’ Room whether the lady in question was still there. The girl went away and presently returned to say that the lady had changed her costume in the cloak-room and had gone out half an hour previously.”

“Oh, Bunter, Bunter. Didn’t you spot the suitcase or whatever it was when she came out again?”

“Excuse me, my lord. The lady had come in earlier in the day and had left an attaché-case in charge of the attendant. On returning, she had transferred her hat and fur to the attaché-case and put on a small black felt hat and a light-weight raincoat which she had packed there in readiness. So that her dress was concealed when she emerged and she was carrying the attaché-case, whereas, when I first saw her, she had been empty-handed.”

“Everything foreseen. What a woman!”

“I made immediate inquiries, my lord, in the region of the hotel and the station, but without result. The black hat and raincoat were entirely inconspicuous, and no one remembered having seen her. I went to the Central Station to discover if she had travelled by any train. Several women answering to the description had taken tickets for various destinations, but I could get no definite information. I also visited all the garages in Liverpool, with the same lack of success. I am greatly distressed to have failed your lordship.”

“Can’t be helped. You did everything you could do. Cheer up. Never say die. And you must be tired to death. Take the day off and go to bed.”

“I thank your lordship, but I slept excellently in the train on the way up.”

“Just as you like, Bunter. But I did hope you sometimes got tired like other people.”

Bunter smiled discreetly and withdrew.

“Well, we’ve gained this much, anyhow,” said Parker. “We know now that this Miss Whittaker has something to conceal, since she takes such precautions to avoid being followed.”
