He picked up the sheets containing the names of the visitors.
`Sincee we have something to go on,' he continued, 'we can use our guests. We know the approximate time of the murder. Hallo!' he called towards the door, and a warder opened it. `Will you go down to the Bloody Tower and send up the sergeant in charge of the police officers who have just arrived?'
'I hope it's Hamper,' he added to his companions. `First, we'll put aside the slips made out by the three people we want to interview ourselves — Mrs Bitton, Mr Arbor, and, just as a precaution, the careful Mrs Larkin. Let's see, Larkin —'

'Doesn't need one,' Sir William growled. `He's got pots.'
"Arrived Southampton, March 4, S.S. Bremen. Duration of stay indefinite. Destination, Villa Seule, Nice, France." He adds, very curtly, "If further information is necessary, suggest communicating with my London solicitors, Messrs Hillton and Dane, Lincoln's Inn Fields." H'm.'

`If you've ever heard any of these other names, gentlemen, sing out; otherwise I'll let the sergeant handle them.
`Mr and Mrs George G. Bebber, 291 Aylesborough Avenue, Pittsburgh, Pa., U.S.A. - Lucien Lefevre, 6o Avenue Foch, Paris. Mlle Clementine Lefevre, as above. - Miss Dorothea Delevan Mercenay, 23 Elm Avenue, Meadville, Ohio, U.S.A. Miss Mercenay adds M.A. to her name, underscored heavily. That's the lot. They sound harmless enough.’
