The Story

The story begins on the ninth birthday of twins Jack and Molly. Among their customary gifts arrives a mysterious brown paper parcel from Aunt Phoebe containing a strange grey pumpkin pincushion. When the children investigate a hidden path at the edge of their garden wood, they step around a giant old tree and emerge into a land completely unlike their own. In this strange country, bathed in a perpetual sunset glow, they meet the kind Old Nancy in her snug cottage. She reveals the true history of their realm: long ago, a delicate royal princess was saved from illness by pumpkin juice, but a malicious dwarf was subsequently trapped inside a Grey Pumpkin, gaining sinister magical powers.

Old Nancy explains that the Grey Pumpkin has returned to exert his dark influence over the country. The only item capable of stripping him of his magic is the elusive Black Leaf, an artifact that appears above ground for only thirteen days each year. Knowing the danger, Jack and Molly courageously volunteer to find the Leaf before the sorcerer can stop them. Old Nancy gifts them a box of enchanted matches to aid their journey, and they set out toward the walled City, where they are welcomed by Glan, a jovial young man who helps them pass safely inside the gates.

In the City, the twins receive maps and guidance from Glan, his father, and Aunt Janet. They are granted an audience with the King at the Palace before setting off to search the surrounding countryside. Their trek proves perilous as the Grey Pumpkin's loyal spies and decoys attempt to thwart their progress. In the third green lane, they are tricked by a girl in green and trapped in a firelit house, but they manage to escape and push forward into the Goblin's Heath. There, hiding in a hollow tree, they meet the goblin Timothy, who provides a critical clue: he has seen the Black Leaf growing inside a flowerpot at the house of Mr. Papingay, Glan's eccentric relative living in the Orange Wood.

Armed with this knowledge, the children brave further trials. A sudden storm and a lost box of matches cause Jack to become separated from Molly, and he falls under the Grey Pumpkin's spell, transformed into a second Grey Pumpkin himself. Distraught but resolute, Molly presses on to Lake Desolate and the home of the blind Miss Lydia. With night falling, Molly bravely retrieves the Black Leaf from under the eyes of the sorcerer's watchers. She leads both Grey Pumpkins to Old Nancy, who identifies the true villain, touches him three times with the Black Leaf, and breaks the curse, restoring Jack to human form. Returning home through the scullery window just before dawn, the twins find Molly's desired silver bangle waiting for her, alongside their parents' knowing smiles.

How It Unfolds

The journey begins After opening their birthday presents, twins Jack and Molly walk past the big tree at the end of their garden wood and find themselves transported into an unfamiliar, sunlit country. They seek shelter in a red-roofed cottage, where Old Nancy tells them the legend of the Grey Pumpkin and the magical Black Leaf that can defeat him.

Inside the City gates Escorted by the cheerful Glan, the children arrive at the City just as the huge gate swings back, narrowly escaping the Pumpkin's influence. They visit Glan's home, meet his quaint family, and gain the King's blessing at the Palace before receiving maps to guide their search across the realm.

Trapped by spies While walking down the third green lane, the twins are lured into a dark passage by a deceptive girl in green working for the Grey Pumpkin. They realize they are trapped when her face turns old and hard, but they summon their courage to break free and make their way to the Goblin's Heath.

A crucial clue Crouching inside a hollow trunk on the heath, the children talk to a skeptical goblin before meeting young Timothy, who admits he saw the Black Leaf sitting on a windowsill in Mr. Papingay's painted house within the Orange Wood.

Separation in the dark A sudden downpour causes Jack to drop his box of Old Nancy's matches, and as he runs back down the hill to retrieve them, he vanishes into the gloom. Molly searches frantically, fighting off a magical wave of sleep against a tree trunk, only to discover Jack has been transformed into a duplicate Pumpkin.

Triumph at Lake Desolate Molly arrives at Lake Desolate, enlists the aid of blind Miss Lydia, and clever strategy allows her to snatch the Black Leaf in the gathering dusk. She brings the leaf to Old Nancy, who identifies the real villain, breaks the spell over both Jack and the realm, and allows the twins to return safely home before morning.

The People

• Molly wants to find the magical Black Leaf to save the strange land and rescue her brother, facing exhaustion, deceptive decoys, and magical dark forces; her bravery and unwavering determination transform her from an ordinary young girl into the celebrated savior of the realm.
• Jack wants to support his twin sister and prove his courage on their unexpected quest, but his impetuous nature leads him to run off into the dark after lost matches, leaving him vulnerable to the Grey Pumpkin's spell until he is freed by Molly's triumph.
• Old Nancy wants to protect the kingdom from the returned evil and see the Black Leaf recovered; she serves as a wise, comforting guide whose magic matches and vital counsel enable the children to navigate the dangers ahead.
• Glan wants to aid the children and keep his city safe from the Pumpkin's forces; his jovial optimism, practical helpfulness, and lighthearted humor make him an invaluable ally throughout their journey.
• The Grey Pumpkin wants to spread his evil influence across the land and prevent anyone from finding the Black Leaf; his dark magic and network of treacherous spies present a constant threat until his power is forever broken.

In Its Own Voice

“Keep up heart. Laugh at misfortune, remember, and—tss—— We shall win!”

Glan bids the children a cheerful farewell as he ushers them away from danger and toward the next stage of their adventure.

“Are you real?” asked the Goblin.

A small goblin pops his head through a hole in the tree trunk, staring in utter disbelief at Jack and Molly crouching above him.

“Here is the Black Leaf,” said Molly, handing the Leaf to Old Nancy.

Molly steps out before the gathered crowd and the King outside Old Nancy's cottage, delivering the magic artifact that will break the sorcerer's power.
