Just now Ellen and Daisy were down in the kitchen, and Bunting didn’t quite like the sensation of knowing that there was only one pair of stairs between Mr. Sleuth and himself. So he quietly slipped out of the house without telling Ellen that he was going out.
In the last four days Bunting had avoided his usual haunts; above all, he had avoided even passing the time of day to his acquaintances and neighbours. He feared, with a great fear, that they would talk to him of a subject which, because it filled his mind to the exclusion of all else, might make him betray the knowledge—no, not knowledge, rather the—the suspicion—that dwelt within him.
But to-day the unfortunate man had a curious, instinctive longing for human companionship—companionship, that is, other than that of his wife and of his daughter.
This longing for a change of company finally led him into a small, populous thoroughfare hard by the Edgware Road. There were more people there than usual just now, for the housewives of the neighbourhood were doing their Saturday marketing for Sunday. The ex-butler turned into a small old-fashioned shop where he generally bought his tobacco.
Bunting passed the time of day with the tobacconist, and the two fell into desultory talk, but to his customer’s relief and surprise the man made no allusion to the subject of which all the neighbourhood must still be talking.
And then, quite suddenly, while still standing by the counter, and before he had paid for the packet of tobacco he held in his hand, Bunting, through the open door, saw with horrified surprise that Ellen, his wife, was standing, alone, outside a greengrocer’s shop just opposite.
Muttering a word of apology, he rushed out of the shop and across the road.
“Ellen!” he gasped hoarsely, “you’ve never gone and left my little girl alone in the house with the lodger?”
Mrs. Bunting’s face went yellow with fear. “I thought you was indoors,” she cried. “You was indoors! Whatever made you come out for, without first making sure I’d stay in?”
Bunting made no answer; but, as they stared at each other in exasperated silence, each now knew that the other knew.
