It was not Kirk, only a forbidding-looking old woman in faded bonnet and shawl—a typical gin-drinking hag of a type one may see in hundreds in that neighbourhood. I had followed her down into Cleveland Street, where she turned to the left, when it suddenly occurred to me that, in my absence, Kirk might make his exit. Therefore I rather foolishly abandoned pursuit, and retraced my steps.

Judge my chagrin, my utter disgust with myself when, on returning, I failed to recognise from which house the woman had come! In that puzzling pall of fog, which grew thicker and more impenetrable every moment, I hesitated to decide which of three or four houses was the place whence the woman’s cries had emanated.

That hesitation was fatal to my success. In my excitement I had taken no notice of the number upon the door, and now I paced backwards and forwards before the railings of four houses, all almost exactly similar, all in darkness, all equally dingy and mysterious. Which of those houses held Kershaw Kirk I knew not, neither could I decide from which of the four had come those despairing cries.

I had been a fool, a very great fool, for not going boldly to the door and demanding an explanation, even though I might have received a rough handling, alone and unarmed as I was. So I returned to the street-lamp and tried to recognise the house from the point where I had stood when the first cry had fallen upon my ears. But, alas! again I could not decide.

My impulse to follow the woman had been my undoing, for I somehow felt a strong conviction that Kirk had escaped during my absence in Cleveland Street, for though I waited in that dense and choking blackness beneath the red lamp of a surgery at the further corner for still another hour, he came not.

Therefore I was compelled very reluctantly to grope my way back into the Tottenham Court Road, where at last I found a hansom, and with a man leading the horse, I fell asleep as we went westward, so fagged and exhausted was I by that long and unpleasant vigil.

The wife of a motorist like myself is used to her husband’s late hours, therefore I had little difficulty in excusing myself to Mabel, yet when I retired to bed no sleep came to my eyes.

That woman’s shrill, despairing cry rang ever in my ears. Those words of hers were so mysterious, so ominous.

You’ve killed me, just as you killed my dear father!”

Should I go to the police in the morning and make a clean breast of the whole affair?
