Footprints in the Jungle by W.S. Maugham

It was in Malaya that I met the Cartwrights. I was staying with a man called Gaze who was head of the police and he came into the billiard-room, where I was sitting, and asked if I would play bridge with them. The Cartwrights were planters and they came to Malaya because it gave their daughter a chance of a little fun. They were very nice people and played a very pleasant game of bridge. I followed Gaze into the cardroom and was introduced to them.
Mrs. Cartwright was a woman somewhere in the fifties. I thought her a very agreeable person. I liked her frankness, her quick wit, her plain face. As for Mr. Cartwright, he looked tired and old. He talked little, but it was plain that he enjoyed his wife's humour. They were evidently very good friends. It was pleasing to see so solid and tolerant affection between two people who were almost elderly and must have lived together for so many years.
When we separated, Gaze and I set out to walk to his house.
"What did you think of the Cartwrights?" he asked me.
"I liked them and their daughter who is just the image of her father."
To my surprise Gaze told me that Cartwright wasn't her father. Mrs. Cartwright was a widow when he married her. Olive was born after her father's death.
And when we came to Gaze's house he told me the Cartwrights' story.
"I've known Mrs. Cartwright for over twenty years," he said slowly. "She was married to a man called Bronson. He was a planter in Selantan. It was a much smaller place than it is now, but they had a jolly little club, and we used to have a very good time. Bronson was a handsome chap. He hadn't much to talk about but tennis, golf and shooting; and I don't suppose he read a book from year's end to year's end. He was about thirty-five when I first knew him, but he had the mind of a boy of eighteen. But he was no fool. He knew his work from A to Z. He was generous with his money and always ready to do anybody a good turn.
One day Mrs. Bronson told us that she was expecting a friend to stay with them and a few days later they brought Cartwright along. Cartwright was an old friend of Bronson's. He had been out of work for a long time and when he wrote to Bronson asking him whether he could do anything for him, Bronson wrote back inviting him to come and stay till things got better. When Cartwright came Mrs. Bronson told him that he was to look upon the place as his home and stay as long as he liked. Cartwright was very pleasant and unassuming; he fell into our little company very naturally and the Bronsons, like everyone else, liked him."
"Hadn't the Bronsons any children at that time?" I asked Gaze.
"No," Gaze answered. "I don't know why, they could have afforded it. Bronson was murdered," he said suddenly.
"Killed?"
"Yes, murdered. That night we had been playing tennis without Cartwright who had gone shooting to the jungle and without Bronson who had cycled to Kabulong to get the money to pay his coolies' their wages and he was to come along to the club when he got back. Cartwright came back when we started playing bridge. Suddenly I was called to police sergeant outside. I went out. He told me that the Malays had come to the police station and said that there was a white man with red hair lying dead on the path that led through the jungle to Kabulong. I understood that it was Bronson.
For a moment I didn't know what to do and how to break the news to Mrs. Bronson. I came up to her and said that there had been an accident and her husband had been wounded. She leapt to her feet and stared at Cartwright who went as pale as death. Then I said that he was dead after which she collapsed into her chair and burst into tears.
When the sergeant, the doctor and I arrived at the scene of the accident we saw that he had been shot through the head and there was no money about him. From the footprints I saw that he had stopped to talk to someone before he was shot. Whoever had murdered Bronson hadn't done it for money. It was obvious that he had stopped to talk with a friend.
Meanwhile Cartwright took up the management of Bronson's estate. He moved in at once. Four months later Olive, the daughter, was born. And soon Mrs. Bronson and Cartwright were married. The murderer was never found. Suspicion fell on the coolies, of course. We examined them all – pretty carefully – but there was not a scrap of evidence to connect them with the crime. I knew who the murderer was..."
"Who?"
"Don't you guess?"

1. І все ж воно наймиліше у світі, це непоказне село на великій рівнині… Тут пройшло твоє дитинство. Тут учився ти в школі. Тут привчали тебе до роботи. Тут навчився любити світ, і людей, і музику, і літературу. Небо, і зорі, і місяць, і перші радощі, і перші печалі - усе для тебе почалося тут, усе ввійшло й лишилося в тобі навіки. Усе, із чого складається людське життя й сама людина (О. Сизоненко).
2. Був пишний травневий вечір. Сонце заходило за сизу легеньку хмарку й неначе обвело її навкруги золотим, лискучим обручиком. Синє небо було прозоре та глибоке, неначе вода коло берега в морі. На небі подекуди плавали білі хмарки, як лебеді. Покроплена дощиком земля ніби дихала пахощами весняних квіток (І. Нечуй-Левицький).
3. Прийшла осінь. У зелені коси беріз вплелися золоті стрічки. Різнобарвним полум’ям горять осики, дикі груші. Червоніють китиці ягід на горобинах. На лісовій ліщині дозріли горіхи. Важкі коричневі жолуді падають з дубів. Лісовим мешканцям настав час заготовляти на зиму харчі (О. Пархоменко).​
