ten o'clock
* * * * * Afterwards I learned how it was that Cunningham , with two detectives from Scotland Yard , had arrived in the very `` nick of time . '' His statements to the police authorities had been necessarily so elaborate , and had been deemed so extraordinary , that it had taken some time to create the desired impression at headquarters . He had been still at `` The Yard '' when my wire had arrived . When at last he had induced the `` powers that be '' to grant a warrant for Wildred 's arrest on suspicion of having murdered Harvey Farnham , and to send a couple of men to the House by the Lock , where my telegram had announced that he was probably to be found , it was too late to catch anything save the ten o'clock train . Having reached the door of the grim old mansion , Karine 's cries for help , ringing out upon the night through the broken skylight , had told them in which direction to proceed , and they had used the same method of surmounting the obstacles which I had adopted and left for them . The servant was secured , but Wildred , seeing with his usual quickness that all hope of escape was over , had shot himself through the heart before the officers could reach him . So died a man who had accomplished the death of many another , and through his humble accomplice -LRB- who now breaks stones at Portland -RRB- , and the wretched wife found prisoned in a room upstairs , the secrets of his numerous crimes and the dark House by the Lock were revealed .
