夫人は横丁の二階の窓に夫を見つける。夫は激しく手を動かした後に突然見えなくなり、夫人はその服装の違いにも気づく。
"If you remember, Monday was an exceedingly hot day, and Mrs. St. Clair walked slowly, glancing about in the hope of seeing a cab, as she did not like the neighbourhood in which she found herself. While she was walking in this way down Swandam Lane, she suddenly heard an ejaculation or cry, and was struck cold to see her husband looking down at her and, as it seemed to her, beckoning to her from a second-floor window. The window was open, and she distinctly saw his face, which she describes as being terribly agitated. He waved his hands frantically to her, and then vanished from the window so suddenly that it seemed to her that he had been plucked back by some irresistible force from behind. One singular point which struck her quick feminine eye was that although he wore some dark coat, such as he had started to town in, he had on neither collar nor necktie.
「覚えているだろうが、月曜日はひどく暑かった。夫人はその辺りが気に入らず、馬車が見つからないかと周りを見ながら、ゆっくり歩いていた。そうしてスワンダム横丁を歩いていると、不意に叫び声のようなものが聞こえた。見ると夫が二階の窓から見下ろし、自分を手招きしているようで、ぞっとしたという。窓は開いていて顔もはっきり見えたが、その顔はひどく取り乱していたと、夫人は説明している。夫は彼女へ激しく両手を振り、それから何か逆らえない力で後ろへ引かれたように、突然窓から姿を消した。夫人の敏い目を引いた奇妙な点が一つある。都心へ出たときと同じような暗い色の上着を着ていたが、付け襟もネクタイも着けていなかったんだ。
