The woman stopped to look into a shop window. Miss Climpson hesitated to come closer. If Mary Whittaker was at large, then—why then the kidnapping had been done with her own consent. Puzzled, Miss Climpson determined to play a waiting game. The woman went into the shop. The friendly chemist’s was almost opposite. Miss Climpson decided that this was the moment to reclaim her latchkey. She went in and asked for it. It had been put aside for her and the assistant produced it at once. The woman was still in the shop over the way. Miss Climpson embarked upon a long string of apologies and circumstantial details about her carelessness. The woman came out. Miss Climpson gave her a longish start, brought the conversation to a close, and fussed out again, replacing the glasses which she had removed for the chemist’s benefit.
The woman walked on without stopping, but she looked into the shop windows from time to time. A man with a fruiterer’s barrow removed his cap as she passed and scratched his head. Almost at once, the woman turned quickly and came back. The fruiterer picked up the handles of his barrow and trundled it away into a side street. The woman came straight on, and Miss Climpson was obliged to dive into a doorway and pretend to be tying a bootlace, to avoid a face to face encounter.
Apparently the woman had only forgotten to buy cigarettes. She went into a tobacconist’s and emerged again in a minute or two, passing Miss Climpson again. That lady had dropped her bag and was agitatedly sorting its contents. The woman passed her without a glance and went on. Miss Climpson, flushed from stooping, followed again. The woman turned in at the entrance to a block of flats next door to a florist’s. Miss Climpson was hard on her heels now, for she was afraid of losing her.
Mary Whittaker—if it was Mary Whittaker—went straight through the hall to the lift, which was one of the kind worked by the passenger. She stepped in and shot up. Miss Climpson—gazing at the orchids and roses in the florist’s window—watched the lift out of sight. Then, with her subscription card prominently in her hand, she too entered the flats.
There was a porter on duty in a little glass case. He at once spotted Miss Climpson as a stranger and asked politely if he could do anything for her. Miss Climpson, selecting a name at random from the list of occupants in the entrance, asked which was Mrs. Forrest’s flat. The man replied that it was on the fourth floor, and stepped forward to bring the lift down for her. A man, to whom he had been chatting, moved quietly from the glass case and took up a position in the doorway. As the lift ascended, Miss Climpson noticed that the fruiterer had returned. His barrow now stood just outside.
The porter had come up with her, and pointed out the door of Mrs. Forrest’s flat. His presence was reassuring. She wished he would stay within call till she had concluded her search of the building. However, having asked for Mrs. Forrest, she must begin there. She pressed the bell.
At first she thought the flat was empty, but after ringing a second time she heard footsteps. The door opened, and a heavily over-dressed and peroxided lady made her appearance, whom Lord Peter would at once—and embarrassingly—have recognised.
“I have come,” said Miss Climpson, wedging herself briskly in at the doorway with the skill of the practised canvasser, “to try if I can enlist your help for our Mission Settlement. May I come in? I am sure you—”
“No thanks,” said Mrs. Forrest, shortly, and in a hurried, breathless tone, as if there was somebody behind her who she was anxious should not overhear her, “I’m not interested in Missions.”
She tried to shut the door. But Miss Climpson had seen and heard enough.
