Light washed over the room. It glinted off shards of broken porcelain, pooled in the folds of white linen nightdresses, limned the sides of fallen furniture, and blared like twin beacons off the spectacles of the woman holding the candle.

Miss Climpson stepped into the room, the starched ruffles of her dressing gown rustling stiffly as she moved. Her graying brown hair was confined beneath a nightcap of truly impressive proportions. From his vantage point on the far side of the window, it reminded Turnip of a large muffin. A decidedly distressed muffin.

Furniture and girls in white nightdresses littered the room, none of it where it ought to be. Bits of white porcelain were scattered across the blue carpet from what had once been a particularly ugly china cupid. A Meissen shepherdess lay headless in the hearth. Sally, still lying where she had landed, sprawled on the floor in front of an overturned table, her nightcap squashed to one side and her braid over one shoulder. Lizzy Reid was sitting proudly on the back of some poor sod while Agnes Wooliston attempted to locate his hands so she could string a pink-edged sash around them.

Lizzy looked decidedly pleased with herself. It was impossible to discern how the intruder looked. His face was pressed into the ground, from which emerged, from time to time, the odd moaning noise.

“Oh dear, oh dear, oh dear,” Miss Climpson murmured, surveying the tattered remnants of her domain. “Oh dear. Miss Dempsey?”

Unlike the girls, Miss Dempsey was still fully dressed, but her hair had burst its pins, unraveling down her back in a burst of congealed sunshine. It looked, somehow, more dramatic against the demure gray of her day dress than it would have had she been in a nightdress like the others. Turnip had never seen her hair down before; it had always been ruthlessly coiled away, stuck about with pins, with a bonnet squashed down on top of it for good measure. He had known it was blond, but he would never have imagined it would be quite so exuberant.

But, then, that was Miss Dempsey all over, wasn’t it? She pretended to be all shy and quiet, and then there she was, chasing down prowlers in the middle of the night.

At the moment, she was holding a chair up in front of her like a lion-keeper at the Tower, prepared to hold the villain at bay should he make another rush for the window.

She very slowly lowered the chair to the ground as she turned to face the headmistress. “Miss Climpson? I’m afraid we’ve had something of an, er, incident.”

Lizzy Reid giggled.

Sally flapped a hand to shush her.

Miss Climpson blinked behind her thick spectacles, her candle making a slow arc as she took in the scene in front of her. “Is that my china cupid?” she asked first, and then, “Is that a man beneath Miss Reid?”

“I am afraid so,” said Miss Dempsey.

Miss Climpson shook her head. “Roaming around the school in the middle of the night, breaking objets d’art, sitting on strange men. Girls! What do you have to say for yourselves?”

“The cupid was already broken when we got here?” suggested Agnes.

“Please.” Miss Dempsey placed herself between her charges and the headmistress. “Let me explain.”

Sally stepped forward in front of Miss Dempsey. “We heard noises, Miss Climpson. So we asked Miss Dempsey to investigate.”

“Just to be safe,” chimed in Lizzy Reid from her position on top of the prowler. “One can’t be too careful in these dangerous times.”

“True, true, true,” agreed Miss Climpson, her stiff ruffles rustling. “But there is still no call for sitting on him.”

“It was only until we could find something with which to tie him.” Agnes Wooliston rushed to her friend’s defense.

The intruder groaned.

Miss Climpson released a short exhalation of air that might have been a sigh. “Miss Reid?”

Lizzy looked at her with wide, innocent eyes. “Yes?”

“We do not sit on people in this establishment. Settees are for sitting; chairs are for sitting; not — ”

“Hideous midnight intruders?” suggested Lizzy helpfully.

“Even those, even those.” It was a sign of Miss Climpson’s agitation that she said it only twice, not three times. “Kindly remove yourself from that man’s person, Miss Reid. Not later, not soon, but right now.”

Lizzy scrambled off the recumbent intruder, who seemed considerably flatter than when he had entered. He looked as though he were trying to become one with the carpet.

Miss Climpson wagged a finger at Lizzy. “That sort of thing is dreadful for your posture. You know what I always say. A crooked back makes for a crooked mind!”

“Yes, Miss Climpson,” chorused all three girls.

“But Miss Climpson,” ventured Agnes. “What about the intruder?”

Miss Climpson frowned down at the prone man. “I suppose we could ask the gardener to take him out. He doesn’t go at all with the rest of the drawing room. He would be very hard to explain to parents when they came to call.” Taking up the fireplace poker, which was lying, in the aftermath of the fray, between an overturned chair and the broken shepherdess, she prodded the man gently in the side. “Sir? Sir?”

The man groaned again.

“Now, now,” prodded Miss Climpson. “It isn’t at all healthy to lie on your stomach like that. It impedes both the digestion and the flow of air to the brain.”

It might have been concern for his digestion that got the man moving, or it might have been the tip of the poker being applied to his side. With a little help from Miss Climpson’s poker, he levered himself slowly up onto his elbows, shaking his head from side to side as though to clear it.

Beneath the tousled mess of hair, his lips moved. His voice was scratchy and just barely audible. “I can make-a dee explanation.”

Everyone stared at him.

“Oh, Lord,” gasped Lizzy. “It’s the music master.”

And so it was. His hair was all about his face and one of his mustachios had come loose in the fray, but it was still, unmistakably, the same man who had been playing the lute at Farley Castle the week before.

Turnip frowned at the music master. It wasn’t beyond the realm of comprehension that the music master might be their spy. He had a foreign name, a strange accent, and access to both the school and Farley Castle. But why sneak in at dead of night when he had perfectly legitimate access by day? No one had ever accused Turnip of being a master of common sense — quite the contrary, in fact — but even he could see that.

Miss Climpson waved her candle at the recumbent music master. “Signor Marconi? What are you doing here?”

“Errrrrr,” groaned Signor Marconi.

Not much of an excuse, that, but to be fair, he had until quite recently had a well-fed sixteen-year-old perched on his back.

“Miss Dempsey,” said Miss Climpson. “Help Signor Marconi to a chair. Proper posture is very important to the workings of the mind. It’s all about the flow of the blood.”

Miss Dempsey obediently stepped forward as instructed. The music master clutched at the hand she extended, nearly sending them both reeling as he staggered clumsily to his feet. Miss Dempsey yanked him to his feet with less than complete solicitude.

“What were you doing lurking about down here?” Miss Dempsey demanded, with some asperity. “Why didn’t you simply make yourself known when you saw me?”

“I came-a for da music,” he said in wounded tones. “Den de girls, they jump on me and break-a my bones. It is dee insult to my art.” As he spoke, his right mustachio dropped off entirely.

Miss Dempsey folded her arms across her chest. “No one would have jumped on anyone if you had identified yourself when I asked.”

“Yes, yes,” said Miss Climpson distractedly, waving Miss Dempsey to silence. “You came for your music. Your music?”

“I give-a dee lesson tomorrow morning. I need-a de music.” Signor Marconi seemed to have rediscovered his Italian accent.

Even to Turnip’s ears, his excuse sounded as phony as his mustachios.

“Where,” asked Miss Dempsey, “is this music?”

Signor Marconi looked from left to right, as though hoping that it might materialize of its own accord. “In the music room?” he said hopefully. Belatedly remembering to look aggrieved, he drooped back in his chair. “All I wanted was to fetch-a de music and go, when de harpies, they, er, dey attack-a me, with de tooth and de claw.”

“Tooth?” demanded Sally indignantly. “Claw? I never laid a hand on the man.”

“I only sat on him,” said Lizzy beatifically. “No teeth or claws involved.”

Agnes looked at her fingernails. “Mine are too short to be claws.”

“Girls,” said Miss Dempsey, and they subsided.

“How did you get in, Signor Marconi?” asked Miss Climpson. “The building is meant to be locked.”

“Meant” being the operative word. As far as Turnip could tell, the structure was as porous as a hunk of cheap cheese. They could start charging a toll for all the people coming in and out at night and save on the tuition.

Signor Marconi’s eyes darted around and caught on the flapping curtains. He flung out an arm, pointing at the window for all he was worth. “Through the — er, da window. I came in-a through da window.”

Not this window, he hadn’t. Turnip could have vouched for that if he hadn’t been crouching beneath said window. Of course, if he hadn’t been crouching beneath the window, he wouldn’t have been in a position to vouch for anything of the kind. It was quite the tangle.

“Why would you do a thing like that?” asked Miss Climpson, in what appeared to be genuine confusion.

“Because da door, it was a-closed.”
