The superintendent lit a cigar after he had replaced the receiver, and thoughtfully toasted his slippered feet before the fire. Presently he rose, turned over the leaves of a time-table, and discovering that Dalehurst possessed no railway station, discarded it in favour of a gazetteer. From that he found that the village was four miles from Deepnook, and the time-table again consulted showed him that he could reach the latter place in a couple of hours from Waterloo. Before he went to bed that night he packed the kit-bag that had accompanied him in most of his wanderings all over the globe. Other things than clothes found a place in its depths, among them a jemmy, some putty, and a glazier's diamond. The superintendent had an idea that they might be more effective than a search warrant. Yet, as he turned the key, he realised that the energy and the efforts of both himself and Green might be wasted. There was a possibility that it was a blind trail--that Grell had contrived the whole thing as a blind, and had slipped out of the net that had been drawn for the brown motor-car. The thought induced Foyle to telephone through to headquarters to order a fresh warning to be wired through to the police at all the ports. He believed in leaving as little as possible to chance. The night staff was still on duty when he reached Scotland Yard the next morning. The detective-inspector in charge stared at a corpulent man clad in a Norfolk jacket, knickerbockers of brown tweed, whose heavy boots clanged along the corridor. The hair, moustache, and eyebrows of the intruder were a shiny black, and a little trimming with scissors and a judicious use of a comb and brush had altered the appearance of the superintendent's face as completely as the clothes had altered his figure. He was no believer in stage disguises. False beards and wigs were liable to go wrong at critical moments. He nodded reassuringly to the inspector and placed his kit-bag on the floor. "It's all right, I'm Foyle right enough. I'm thinking of a change of air for a day or two," was all the explanation he vouchsafed. "I want to just run through my letters and catch the nine-ten train from Waterloo. I'll leave a note over for Mr. Mainland, who'll take charge while I'm away." He went methodically through the heavy morning's correspondence, pencilling a few notes here and there on the letters, and sorting them into baskets ranged on the table as he finished. Precisely at a quarter to nine he touched a bell, and gave a few brief instructions. Then, carrying his bag, he descended the flight of steps at the front entrance and walked briskly along the Embankment. As he crossed the footway of Hungerford Bridge, a biting wind swept up the river and he shivered, warmly clad though he was. One of his own men passed without recognising him, and the superintendent smiled to himself.
