Pulling up his coat collar in an effort to shield himself from the persistence of the rain, Caldew expressed his disappointment at the failure of the night's expedition in a bitter jibe at his bad luck. At first he thought he would wait a little longer on the watch, then he changed his mind as he glanced at the unpromising night, and decided that it wasn't worth while. He lived in Edgeware Road, so he shook hands with Colwyn and set out for the Underground at King's Cross. Colwyn returned to the _Angel_ to look for a taxi-cab. The fog was lifting, and crowds were emerging from the cinemas and a music-hall with the fatigued look of people who have paid in vain to be entertained. Outside the music-hall some taxi-cabs were waiting for the more opulent patrons of refined vaudeville who had been drawn within by the rare promise of an intellectual baboon, reputed to have the brains of a statesman, which shared the honours of "the top of the bill" with two charming sisters from a West End show. The drivers of the taxi-cabs said they were engaged, and uncivilly refused to drive the detective to Ludgate Circus. A Bermondsey omnibus came plunging through the fog, scattering the filth of the road on the hurrying pleasure-goers, and stopped at the corner to add to its grievous load of damp humanity. Those already in the darkened interior sat stiffly motionless, like corpses in a mortuary wagon, as the new-comers scrambled in, scattering mud and water over them, feeling for the overhead straps. Colwyn did not attempt to enter. Even a Smithfield tram-car would be better than the interior of a 'bus on a wet night. An ancient four-wheeler went past, crawling dejectedly homeward. The driver checked his gaunt horse at the sight of Colwyn standing on the kerb-stone, and raised an interrogative whip. He added a vocal appeal for hire based on the incredible assumption that a man must live, which he proclaimed with a whip elevated to the sodden heavens, calling on a God, invisible in the fog, to bear witness that he hadn't turned a wheel that night. The phrasing of the appeal helped Colwyn to recall that it was the same cabman who had accosted Philip Heredith and himself on the night they had motored to the moat-house. He engaged the cab and entered the dark interior. The whip which had been uplifted in pious aspiration fell in benedictory thanks on the bare ribs of the horse. The equipage jolted over the _Angel_ crossing into the squalid precincts of St. John's Street. In a short time the overpowering smell of slaughtered beasts announced the proximity of Smithfield. The cab turned down Charterhouse Street towards Farringdon Market, and a little later pulled up under the archway at Ludgate Circus. "I leaves it to you, sir," said the cabman, in a husky whisper. His expectant palm closed rigidly on the silver coins, and his whip fell on the lean sides of his horse with a crack like a pistol shot as he wheeled round, leaving the detective standing in the road.
