"Inside the carriage she finds a disguise--dress, wig, everything complete--a disguise easy to slip on over her ball-gown and sufficient to baffle a detective half a yard away."

"You shall have it, sir! My heart bleeds for that young lady!" cried Mr. Crowninshield, and he grasped my hand in the noblest fashion. He had been a baritone in his day. "Besides," and he descended swiftly to the mere level of a human being, "I have a score against Master Juan, and I should like to get a little of my own back."

That was precisely the point of view upon which I had counted. Throughout his first term of office Juan Ballester had hired a box at the Opera. Needless to say, he had never paid for it, and Mr. Crowninshield unwisely pressed for payment. When requests failed, Mr. Crowninshield went to threats. He threatened the Law, the American Eagle, and the whole of the United States Navy. Ballester's reply had been short, sharp, and decisive. The State telephone system was being overhauled. Juan Ballester moved the Exchange to a building on the other side of the Opera House, and then summarily closed the Opera House on the ground that the music prevented the operators from hearing the calls. It was not astonishing that Mr. Crowninshield was eager to help Olivia Calavera. He lit a candle and led me through his private door across the empty theatre, ghostly with its sheeted benches, to the wardrobe-room. We chose a nun's dress, long enough to hide Olivia's gown, and a coif which would conceal her hair and overshadow her face.

"In that her own father wouldn't know her. It will be dark; the Quay is ill-lighted, she has only to shuffle like an old woman; she will go third-class, of course, in the train. Who is to see her off?"

"No one," I answered. "I dread that half-hour in the train for her without a friend at her side. The Quay will be watched, too. She must run the gauntlet alone. Luckily there will be a crowd of harvesters returning to Spain. Luckily, also, she has courage. But it will be the worst of her trials. My absence would be noticed. I can't go."

"No, but I can!" cried Mr. Crowninshield. "An old padre seeing off an old nun to her new mission--eh? Juan will be gritting his teeth in the morning because I am an American citizen."

Mr. Crowninshield was aflame with his project. He took a stick and tottered about the room in the most comical fashion. "I will bring the carriage myself to the garden door," said he. "I will be inside of it. My property man--he comes from Poughkeepsie--shall be the driver. I will dress the young lady as we drive slowly to the station, and Sister Pepita and the Padre Antonio will direct their feeble steps to the darkest corner of the worst-lit carriage in the train."

I thanked him with all my heart. It had seemed to me terrible that Olivia should have to make her way alone on board the steamer. Now she would have someone to enhearten and befriend her. I met Olivia once at the house of Enrique Gimeno, and made her acquainted with the scheme, and on the night of the sixteenth the steamship agent rang me up on the telephone.

"The Ariadne will arrive at nine to-morrow night. The passengers will leave Santa Paula at half-past ten. Good luck!"

I went to the window and looked out over the garden. The marquee was erected, the fairy lights strung upon the trees, a set piece with the portrait of Juan Ballester and a Latin motto--semper fidelis--raised its monstrous joinery against the moon. Twenty-four hours more and, if all went well, Olivia would be out upon the high seas, on her way to Trinidad. Surely all must go well. I went over in my mind every detail of our preparations. I recognised only one chance of failure--the chance that Mr. Crowninshield in his exuberance might over-act his part. But I was wrong. It was, after all, Olivia who brought our fine scheme to grief.
