He carried out his plan, with much discomfort to himself, for he hated early rising, but the ruse gained him nothing. Mrs. Biggs arrived and took his place. Not so much as a day was lost to Jane. By the end of the week, his irritation and his curiosity had grown to such a size that he was persuading himself that he owed it to himself to know where she went. After all she was his wife; he had a right to know what she was doing. So for two mornings when Jane went to the tenement room to write, Jerry sauntered along far enough behind her to escape detection. Both days he saw her disappear up the tenement stairs, and half an hour of waiting did not see her come down again. But Mrs. Biggs was at the studio. What could Jane be doing in that building? The third day he was rewarded for his trouble. Shortly after she had entered the building he saw Christiansen arrive. He evidently whistled up the tube, for she came down at once and they went away, talking earnestly. Jane seemed excited. Jerry rushed around the corner and up the block. At the next crossing he came sauntering toward them. "Oh, Jerry!" said Jane, surprised but unembarrassed. "Good-morning, Mr. Christiansen," said Jerry shortly. "You're an early riser." "Yes." "Do you, like my wife, take your exercise at this hour?" "Sometimes. I exercise all day. I always walk." "Mr. Christiansen is going with me to do an errand," Jane said. "Don't let me detain you," Jerry remarked. "We _are_ in rather a hurry," said Jane unconcernedly. They went on their way, leaving Jerry to a fine, old-fashioned, male rage. Here was a pretty how-de-do, where his own wife cavalierly dismissed him to go off with her lover. There was no shadow of doubt in his mind that Christiansen was in love with Jane, although, in spite of all the evidence, he could not reconcile it to himself that Jane was in love with Christiansen. But the tenement house, the rendezvous; what did it all mean? Then he went back home and ascended to the nursery. "Has Mrs. Paxton a key to your apartment, Mrs. Biggs?" he inquired casually. "Yes, sir. She has to have it to get into her room there. We keep it under the mat." "Her room?" "Yes, sir. Didn't you know she kept her old room with me? Oh, mebbe I shouldn't ha' told ye, sir." "Oh--I suppose she must have told me; I've just forgotten it. Do her friends go there? She's never asked me." "Oh, no, sir; nobody comes there. A gentleman used to come, but that was before her marriage." "Big man, gray-black hair?" "Yes, sir, that's him." "Baby been asleep all morning?" he forced himself to ask, casually, as if the other conversation was purely incidental.
