“According to Thomas Mann,” Peter said, “‘Great artists are great invalids.’ ”

And there on the blanket, you set something. There, surrounded by tubes of paint and paintbrushes, was a big rhinestone brooch. Big around as a silver dollar, the brooch was clear glass gems, tiny polished mirrors in a pinwheel of yellow and orange, all of them chipped and cloudy. There on the plaid blanket, it seemed to explode the sunlight into sparks. The metal was dull gray, gripping the rhinestones with tiny sharp teeth.

Peter said, “Are you hearing any of this?”

And Misty picked up the brooch. The sparkle reflected straight into her eyes, and she was blinded, dazzled. Disconnected from everything here, the sun and weeds.

“It’s for you,” Peter said, “for inspiration.”

Misty, her reflection showed shattered a dozen times in every rhinestone. A thousand pieces of her face.

To the sparkling colors in her hand, Misty said, “So tell me.” She said, “How did Maura Kincaid’s husband die?”

And Peter, his teeth green, he spit green into the tall weeds around them. The black cross on his face. He licked his green lips with his green tongue, and Peter said, “Murder.” Peter said, “They murdered him.”

And Misty started to paint.

JUST FOR THE RECORD, the cruddy old library with its wallpaper peeling at every seam and dead flies inside all the milk-glass lights hanging from the ceiling, everything you can remember is still here. If you can remember it. The same shabby world globe, yellowed to the color of soup. The continents carved into places like Prussia and the Belgian Congo. They still have the framed sign that says “Anyone Caught Defacing Library Books Will Be Prosecuted.”

Old Mrs. Terrymore, the librarian, she wears the same tweed suits, except now she has a lapel button as big as her face that says “Find Yourself in a New Future with Owens Landing Financial Services!”

What you don’t understand, you can make mean anything.

People all over the island are wearing this same kind of button or T-shirt, selling some advertising message. They get a little prize or cash award if they’re seen wearing it. Turning their bodies into billboards. Wearing baseball caps with 1-800 telephone numbers.

Misty’s here with Tabbi, looking for books about horses and insects her teacher wants her to read before Tabbi starts seventh grade this fall.

No computers. No connections to the Internet or database terminals means no summer people. No lattes allowed. No videotapes or DVDs to check out. Nothing permitted above a whisper. Tabbi’s off in the kids’ section, and your wife’s in her own personal coma: the art book section.

What they teach you in art school is that famous old masters like Rembrandt and Caravaggio and van Eyck, they just traced. They drew the way Tabbi’s teacher won’t let her. Hans Holbein, Diego Velazquez, they sat in a velvet tent in the murky dark and sketched the outside world that shined in through a small lens. Or bounced off a curved mirror. Or like a pinhole camera, just projected into their tiny dark room through a little hole. Projecting the outside world onto the screen of their canvas. Canaletto, Gainsborough, Vermeer, they stayed there in the dark for hours or days, tracing the building or naked model in the bright sunlight outside. Sometimes they even painted the colors straight over the projected colors, matching the shine of a fabric as it fell in projected folds. Painting an exact portrait in a single afternoon.

Just for the record, camera obscura is Latin for “dark chamber.”

Where the assembly line meets the masterpiece. A camera using paint instead of silver oxide. Canvas instead of film.

They spend all morning here, and at some point Tabbi comes to stand next to her mother. Tabbi’s holding a book open in her hands and says, “Mom?” Her nose still on the page, she tells Misty, “Did you know it takes a fire of at least sixteen-hundred degrees lasting seven hours to consume the average human body?”

The book’s got black-and-white photos of burn victims curled into the “pugilist position,” their charred arms pulled up in front of their faces. Their hands are clenched into fists, cooked by the heat of the fire. Charred black prizefighters. The book’s called Fire Forensic Investigation .

Just for the record, today’s weather is nervous disgust with tentative apprehension.

Mrs. Terrymore looks up from her desk. Misty tells Tabbi, “Put it back.”

Today in the library, in the art section, your wife’s touching books at random on the reference shelf. For no reason, she opens a book, and it says how when an artist used a mirror to throw an image onto canvas, the image would be reversed. This is why everyone in so many old-master paintings is left-handed. When they used a lens, the image would be upside down. Whatever way they saw the image, it was distorted. In this book, an old woodcut print shows an artist tracing a projection. Across the page, someone’s written, “You can do this with your mind.”

It’s why birds sing, to mark their territory. It’s why dogs pee.

The same as the bottom of the table in the Wood and Gold Dining Room, Maura Kincaid’s life-after-death message:

“Choose any book at the library,” she wrote.

Her lasting effect in pencil. Her homemade immortality.

This new message is signed Constance Burton .

“You can do this with your mind.”

At random, Misty pulls down another book and lets it fall open. It’s about the artist Charles Meryon, a brilliant French engraver who became schizophrenic and died in an asylum. In one engraving of the French Marine Ministry, a classic stone building behind a row of tall fluted columns, the work looks perfect until you notice a swarm of monsters decending from the sky.

And written across the clouds above the monsters, in pencil, it says: “We are their bait and their trap.” Signed Maura Kincaid .

With her eyes closed, Misty walks her fingers across the spines of books on the shelf. Feeling the ridges of leather and paper and cloth, she pulls out a book without looking and lets it fall open in her hand.

Here’s Francisco Goya, poisoned by the lead in his bright paints. Colors he applied with his fingers and thumbs, scooping them out of tubs until he suffered from lead encephalopathy, leading to deafness, depression, and insanity. Here on the page is a painting of the god Saturn eating his children—a murky mix of black around a bug-eyed giant biting the arms off a headless body. In the white margin of the page, someone’s written: “If you’ve found this, you can still save yourself.”

It’s signed Constance Burton .

In the next book, the French painter Watteau shows himself as a pale, spindly guitar player, dying of tuberculosis as he was in real life. Across the blue sky of the scene, is written: “Do not paint them their pictures.” Signed Constance Burton .

To test herself, your wife walks across the library, past the old librarian watching through little round glasses of black wire. In her arms, Misty’s carrying the books on Watteau, Goya, the camera obscura, all of them open and nested one inside the next. Tabbi looks up, watching from a table heaped with kids’ books. In the literature section, Misty closes her eyes again and walks, trailing her fingers across the old spines. For no reason, she stops and pulls one out.

It’s a book about Jonathan Swift, about how he developed Meniere’s syndrome and his life was ruined by dizziness and deafness. In his bitterness, he wrote the dark satires Gulliver’s Travels and A Modest Proposal, suggesting the British could survive by eating the increasing flood of Irish children. His best work.

The book falls open to a page where someone has written: “They would have you kill all of God’s children to save theirs.” It’s signed Maura Kincaid .
