"And I knew I must be careful because the police are very clever. But then I'm not really as stupid as people think! If you're very slow and just stare, people think you don't take things in-and sometimes, underneath, you're laughing at them! I knew I could kill John and nobody would know because I'd read in that detective story about the police being able to tell which gun a bullet has been fired from. Sir Henry had shown me how to load and fire a revolver that afternoon. I'd take two revolvers. I'd shoot John with one and then hide it and let people find me holding the other and first they'd think Fd shot him and then they'd find he couldn't have been killed with that revolver and so they'd say I hadn't done it after all!"
She nodded her head triumphantly.
"But I forgot about the leather thing. It was in the drawer in my bedroom. What do you call it, a holster? Surely the police won't bother about that now?"
"They might," said Henrietta. "You'd better give it to me, and I'll take it away with me. Once it's out of your hands, you're quite safe."
She sat down. She felt suddenly unutterably weary.
Gerda said, "You don't look well. I was just making tea."
She went out of the room. Presently she came back with a tray. On it was a teapot, milk jug and two cups. The milk jug had slopped over because it was overfull. Gerda put the tray down and poured out a cup of tea and handed it to Henrietta.
"Oh, dear," she said, dismayed, "I don't believe the kettle can have been boiling."
"It's quite all right," said Henrietta. "Go and get that holster, Gerda."
Gerda hesitated and then went out of the room. Henrietta leant forward and put her arms on the table and her head down on them. She was so tired, so dreadfully tired … But it was nearly done now. Gerda would be safe… as John had wanted her to be safe.
She sat up, pushed the hair off her forehead and drew the teacup towards her. Then at a sound in the doorway she looked up.
Gerda had been quite quick for once.
But it was Hercule Poirot who stood in the doorway.
"The front door was open," he remarked as he advanced to the table, "so I took the liberty of walking in."
"You!" said Henrietta. "How did you get here?"
"When you left The Hollow so suddenly, naturally I knew where you would go. I hired a very fast car and came straight here."
"I see." Henrietta sighed. "You would."
"You should not drink that tea," said Poirot, taking the cup from her and replacing it on the tray. "Tea that has not been made with boiling water is not good to drink."
"Does a little thing like boiling water really matter?"
Poirot said gently, "Everything matters."
There was a sound behind him and Gerda came into the room. She had a workbag in her hands. Her eyes went from Poirot's face to Henrietta's.
Henrietta said quickly:
"I'm afraid, Gerda, I'm rather a suspicious character. M. Poirot seems to have been shadowing me. He thinks that I killed John-but he can't prove it."
She spoke slowly and deliberately. So long as Gerda did not give herself away-Gerda said vaguely, "I'm so sorry. Will you have some tea, M. Poirot?"
"No, thank you, Madame."
Gerda sat down behind the tray. She began to talk in her apologetic conversational way.
"I'm so sorry that everybody is out. My sister and the children have all gone for a picnic. I didn't feel very well, so they left me behind."
"I am sorry, Madame."
Gerda lifted a teacup and drank.
"It is all so very worrying. Everything is so worrying… You see, John always arranged everything and now John is gone…" Her voice tailed off. "Now John is gone…"
Her gaze, piteous, bewildered, went from one to the other.
"I don't know what to do without John.
John looked after me… He took care of me. Now he is gone, everything is gone…
And the children-they ask me questions and I can't answer them properly. I don't know what to say to Terry. He keeps saying, 'Why was Father killed?5 Some day, of course, he will find out why… Terry always has to know. What puzzles me is that he always asks why, not who!"
Gerda leaned back in her chair. Her lips were very blue.
She said stiffly:
"I feel-not very well-if John-John-"
Poirot came round the table to her and eased her sideways down in the chair. Her head dropped forward. He bent and lifted her eyelid. Then he straightened up.
"An easy and comparatively painless death."
Henrietta stared at him.
"Heart? No." Her mind leaped forward.
"Something in the tea… Something she put there herself. She chose that way out?"
Poirot shook his head gently.
"Oh, no, it was meant for you. It was in your teacup."
"For me?" Henrietta's voice was incredulous.
"But I was trying to help her."
"That did not matter. Have you not seen a dog caught in a trap-it sets its teeth into anyone who touches it. She saw only that \ you knew her secret and so you too must die."
Henrietta said slowly:
"And you made me put the cup back on the tray-you meant-you meant her-"
Poirot interrupted her quietly:
