He had no definite plan of action. Every line of inquiry hitherto followed had led to nothing but disappointment. With most of the details concerning the elaborate organization of the Kazmah group either gathered or in sight, the whereabouts of the surviving members remained a profound mystery. From the Chinese no information could be obtained. Distrust of the police resides deep within the Chinese heart; for the Chinaman, and not unjustly, regards the police as ever ready to accuse him and ever unwilling to defend him; knows himself for a pariah capable of the worst crimes, and who may therefore be robbed, beaten and even murdered by his white neighbors with impunity. But when the police seek information from Chinatown, Chinatown takes its revenge—and is silent. Out on the river, above and below Limehouse, patrols watched for signals from the Asiatic quarter, and from a carefully selected spot on the Surrey side George Martin watched also. Not even the lure of a neighboring tavern could draw him from his post. Hour after hour he waited patiently—for Sin Sin Wa paid fair prices, and tonight he bought neither opium nor cocaine, but liberty. Seton Pasha, passing from point to point, and nowhere receiving news of Kerry, began to experience a certain anxiety respecting the safety of the intrepid Chief Inspector. His mind filled with troubled conjectures, he passed the house formerly occupied by the one-eyed Chinaman—where he found Detective-Sergeant Coombes on duty and very much on the alert—and followed the bank of the Thames in the direction of Limehouse Basin. The narrow, ill-lighted street was quite deserted. Bad weather and the presence of many police had driven the Asiatic inhabitants indoors. But from the river and the docks arose the incessant din of industry. Whistles shrieked and machinery clanked, and sometimes remotely came the sound of human voices. Musing upon the sordid mystery which seems to underlie the whole of this dingy quarter, Seton pursued his way, crossing inlets and circling around basins dimly divined, turning to the right into a lane flanked by high eyeless walls, and again to the left, finally to emerge nearly opposite a dilapidated gateway giving access to a small wharf. All unconsciously, he was traversing the same route as that recently pursued by the fugitive Sin Sin Wa; but now he paused, staring at the empty wharf. The annexed building, a mere shell, had not escaped examination by the search party, and it was with no very definite purpose in view that Seton pushed open the rickety gate. Doubtless Kismet, of which the Arabs speak, dictated that he should do so.
