Detective Keeling took his client—a good­looking lady into the back yard of the store together. The lady opened a door in the wall and they entered the small room behind the store. They crossed the room to a locked door.

    Mr. Keeling took some special keys from his pocket. Moments later, one of the keys unlocked the door. The lady went into the store. She said she would hide under the table to keep watch on her husband. Mr. Keeling did not follow her.

    The detective went quickly to the policeman's house. Then the two men hurried to the jewellery store. They looked through the window. The policeman was surprised. He spoke to Mr. Keeling, “I don't understand. You told me, ‘Robbins took a young woman to a restaurant.' Where is she?”

    “There she is!” said Mr. Keeling. He pointed through the window.

    “Do you know the lady with Robbins?” asked the policeman.

    “That's his secret friend,” said Mr. Keeling.

    “No! You're wrong! That's Robbins' wife,” said the policeman. “I've known her for fifteen years.”

    “What?” the detective shouted. His face became pale. “Who is under the table in the store?” He started to kick the door of the jewellery store. Mr. Robbins came to the door and opened it. The policeman and the detective ran into the store.

    “Look under that table!” shouted the detective. “Be quick!”

    The policeman lifted the cloth and put his arm under the table. He pulled out a black dress, a black veil and a woman's wig(假发).

    “Is this young lady your wife?” Mr. Keeling asked the jeweller. He pointed at the woman.

    “Yes! She is my wife!” said Mr. Robbins angrily. “Why did you kick my door? Why are those clothes under my table?”

    “Please check all the jewellery in your store, Mr. Robbins,” the policeman said. “Is anything missing?”

    Some diamond rings and some expensive necklaces were missing. The missing jewellery was worth $800. Later that night, Mr. Keeling was sitting in his office. He was looking through a big book of photographs. They were photographs of criminals. The policeman had brought the book to the detective's office. Suddenly, Mr. Keeling stopped turning the pages. He looked at a picture of a handsome young man with a familiar face.

    The next morning, Mr. Keeling paid the jeweller $800, then closed his office.

    When I told my father that I was moving to Des Moines, Iowa, he told me about the only time he had been there. It was in the 1930s, when he was an editor of the literary magazine of Southern Methodist University（SMU）in Dallas, Texas. He also worked as a professor at SMU, and there was a girl student in his class who suffered from a serious back disease. She couldn't afford the operation because her family was poor.

    Her mother ran a boardinghouse in Galveston, a seaside town near Houston, Texas. She was cleaning out the attic（阁楼）one day when she came across an old dusty manuscript（手稿）. On its top page were the words, “By O. Henry”. It was a nice story, and she sent it to her daughter at SMU, who showed it to my father. My father had never read the story before, but it sounded like O. Henry, and he knew that O. Henry had once lived in Houston. So it was possible that the famous author had gone to the beach and stayed in the Galveston boardinghouse, and had written the story there and left the manuscript behind by accident. My father visited an O. Henry expert at Columbia University in New York, whoauthenticatedthe story as O. Henry's.

My father then set out to sell it. Eventfully, he found himself in Des Moines, meeting with Gardner Cowles, a top editor at the Des Moines Register. Cowles loves the story and bought it on the spot. My father took the money to the girl. It was just enough for her to have the operation she so desperately needed.

My father never told me what the O. Henry story was about. But I doubt that it could have been better than his own story.

Owls and Larks

    Larks are most likely to be healthy, wealthy and wise, according to the old saying.

But those who are early to bed and early to rise do not always have the upper hand, researchers say. They have found that night owls are generally brighter and wealthier than those able to get up early in the morning.

    Experts from the University of Madrid carried out tests on around 1,000 teenagers and found that those who preferred to stay up late proved the kind of intelligence associated with honored jobs and higher incomes. “Larks” or “morning people”, however, often acquired better exam results, possibly because lessons are held at the wrong time of day for night owls. The researchers examined the habits and body clocks of the youngsters to determine whether they liked to stay up late and sleep later in the morning, or preferred to go to bed early and were at their peak in the morning. School performance and inductive(归纳的)intelligence, or problem solving, were measured and academic grades in the major subjects were also taken into account. The results showed that evening types scored higher than morning types on inductive reasoning, which has been shown to be a good estimate of general intelligence and a strong indicator of academic performance. They also had a greater capacity to think conceptually as well as analytically. Such abilities have been linked to innovative(创新的) thinking, more admired occupations and better incomes.

    Famous night owls include President Trump, Obama, Charles Darwin, Winston Churchill, Keith Richards and Elvis Presley. George W. Bush, who is regularly in bed by 10 p.m., Thomas Edison, Napoleon, Condoleezza Rice, who wakes at 4:30 a.m., and Ernest Hemingway are among those known as larks. Jim Horne, professor of psychophysiology at Loughborough University, said, “Evening types tend to be the more active and creative types, the poets, artists and inventors, while the morning types are the deducers(推断者), as are often seen with civil servants and accountants.” A previous study of US Air Force recruits found that evening types were much better at thinking to solve problems than larks.

Photographic self-portraits have existed for as long as cameras have been in human hands. But what about selfies in space? On Twitter last year, NASA astronaut Edwin Aldrin, who famously became the second man to walk on the moon in July 1969, laid claim to a spaceflight first: taking the first selfie in space during the Gemini XII mission in 1966.

"For me, it needs to be digital to be selfie," argues Jennifer Levasseur, a director at the Smithsonian National Air and Space Museum. According to Levasseur, the concept of a selfie is directly linked to internet culture. "The thing that makes a selfie is sharing it," she says.

Still, astronauts have been carrying cameras aboard space vehicles since the 1960s. In 1966, Aldrin used a Hasselblad camera designed specifically for space. Hasselblad also painted the first camera in space a matte(磨砂) black to reduce reflections in the orbiter window. But cameras used in space need to survive extreme conditions, like temperature swings from -149° to 248°F, so Hasselblad painted later model silver.

Astronauts visiting the moon then had to take out the film and leave their camera bodies behind when they returned to Earth, because early space missions were limited by a weight limit on the returned trip. Then a big change in space camera technology came after the space shuttle Columbia broke apart on its return to Earth in 2003, Levasseur notes. "Fear that they'd never be able to bring film back from space and lose all that hard work accelerated the push for digital," she says.

Today, astronauts also have access to internet and social platforms in space and can post true space selfies made using digital cameras. Similarly, space robots are participating in selfie culture, capturing remote pictures of themselves in space or on other planets and sending them back to Earth.
