Two other facts did Inspector Whyland discover. The first, which did not astonish him, was that the letter signed John Lacey had in all probability been typed upon the same machine as had been the envelope in which the numbered counter had been sent to Richard Pargent. The second, which was distinctly perplexing, was that the call to Mr. Briggs had been made from a call-box at Aldersgate station, apparently at the very time when Mr. Martin was known to have been there. Lastly, the automatic was identified as the property of Mr. Martin, and a fingermark on the counter corresponded to an imprint taken from the dead man’s hand.
