one o'clock
Hence it seemed to me certain that the pair of malefactors , having secured the money , would at once make themselves scarce . How , I wondered , could they have known of Jack Marlowe , unless they had watched us both in secret , as seemed most likely . That they would not return again to that house of horror in Bayswater seemed certain . Towards one o'clock we took a taxi off the stand outside White 's and drove to Porchester Terrace , alighting some distance from our destination . We passed the constable strolling slowly in the opposite direction , and when at last we gained the rusty iron gate we both slipped inside , quietly and unobserved . The street lamp in the vicinity lit up the front of the dingy house , therefore fearing observation from any of the servants next door , we moved noiselessly in the shadow of the bushes along the side of the premises , past a small conservatory , many panes of glass of which were broken , and so into the darkness of the small back garden , which seemed knee-deep in grass and weeds , and which , from its position , hemmed in by blank walls , could not be overlooked save from the house itself . All was silence .
