We were soon put out of our suspense. The library was in theory the inviolable sanctuary of the Attorney General, and at Philip's suggestion we began to retreat through the open French windows into the garden. The Seraph and I, however, stood at the end of the file and were caught by Arthur and the Prime Minister before we could escape. Rawnsley had forgotten me during my absence abroad, and we had to be introduced afresh.

"Don't go for a moment," said Arthur, as we made another movement towards the window. "You may be able to help us."

I pulled up a chair and watched Rawnsley fumbling for a spectacle-case. He had aged rather painfully since the day I first met him five-and-twenty years before, as President of the Board of Trade, coming to Oxford to address some political club.

"Sheet of paper? A.B.C., Roden?" he demanded in the quick, staccato voice of a man who is always trying to compress three weeks' work into three days. He had his son's ruthless vigour and wilful assurance without any of Nigel's thin-skinned self-consciousness. "Thanks. Now. My daughter's missing, Mr. Merivale. You may be able to help. Do you know her by sight?"

I mentioned the glimpse I had caught of her at the theatre.

"Quite enough. She left Downing Street yesterday morning at a quarter to ten and was to call at her dressmaker's and come down to Hanningford by the eleven-twenty. We've only two decent trains in the day, and if she missed that she was to lunch in town and come by the four-ten. You left at eleven-fifteen, from platform five. The eleven-twenty goes from platform four. May I ask if you saw anything of her before you left?"

I said I had not, and added that I was so busily engaged in meeting old friends and being introduced to new ones that I had had neither time nor eyes....

"Thank you!" he interrupted, turning to the Seraph. "Mr. Aintree, you know my daughter, and Roden tells me you came down by the four-ten yesterday afternoon. The train slips a coach at Longfield, a few miles beyond Hanningford. Did you by any chance see who was travelling by the slip?"

The Seraph was no more helpful than I had been, and Rawnsley shut the A.B.C. with an impatient slap.

"We must try in other directions, then," he said. "She never left London."
