At Mill Lane Primary, the corridors buzzed with whispers louder than the fire alarm. The famous (and slightly ridiculous) school painting – The Majestic Turnip
The five detectives, already infamous for solving mysteries the adults couldn’t, were called in. Trouble never found them quietly. This time, it arrived with glitter footprints, biscuit crumbs, and a very nervous headteacher.
The Suspects
Mr Tippet But this is far worse! ” he wailed dramatically, clutching his forehead like a Shakespearean actor.
Mrs Crumb
Headteacher Mr Pike
The detectives exchanged glances. It was going to be one of those days!
Clues Begin to Surface
On the floor, Jack’s sharp eyes landed on a half-eaten custard cream, lying like a guilty golden breadcrumb suspiciously close to the bare patch of wall where the painting once hung in pride. Its creamy insides oozed ever so slightly, as though the biscuit itself were sweating under the pressure of being caught at the scene.
Nearby, a glitter trail shimmered like a disco carpet leading straight to the Year 6 classroom. It clung to shoes, stuck in corners, and refused to be brushed away, as though determined to make its presence known. The whole scene had all the subtlety of an army of fairies sneezing glitter bombs until even the floor finally gave up.
Amira began pacing, muttering, piecing together a crime scene under her breath:
❌ Mr Tippet left before 3:30, so he wasn’t around when the painting disappeared.
Oliver: “Let us draw a timeline to track everyone’s movements.”
Step 1:
Step 2:
Step 3:
Emma: “We need to list everyone who entered or left during the 3:15–3:45 pm window!”
Step 1: 15:05 (3:05 pm)
Step 2: half past three (3:30 pm)
Step 3: twenty to four (3:40 pm)
❌ Mrs Crumb was there, but not alone – the student came back at 3:40.
Oliver: “Let us draw a timeline to track everyone’s movements.”
Step 1:

Emma: “We need to list everyone who entered or left during the 3:15–3:45 pm window!”

Step 3: twenty to four (3:40 pm)
❌ Mr Tippet had already gone by then, so all three weren’t together.
Oliver: “Let us draw a timeline to track everyone’s movements.”

Emma: “We need to list everyone who entered or left during the 3:15–3:45 pm window!”

Step 3: twenty to four (3:40 pm)
✅ That’s right!
Biscuit Fractions
On a chair in the hall, Lucy found an open biscuit packet. Out of 20 biscuits, exactly 3/5
❌ 10 is half, not 3/5 eaten.
Jack: “Let us find out how many biscuits make up one fifth first.”
Step 1:
Step 2:
Step 3:
Amira: “Let us use our common sense to check our thoughts.”
Half of the packet would be exactly 10 biscuits. The fraction 3/5 is slightly more than a half. This means more than 10 biscuits were eaten. Use that fact to rule out some of the answers.
❌ 12 would mean only 8 were eaten, not 12.
Jack: “Let us find out how many biscuits make up one fifth first.”
Step 1:
Step 2:
Step 3:
Amira: “Let us use our common sense to check our thoughts.”
Half of the packet would be exactly 10 biscuits. The fraction 3/5 is slightly more than a half. This means more than 10 biscuits were eaten. Use that fact to rule out some of the answers.
❌ 6 suggests just 14 eaten, which doesn’t match 3/5.
Jack: “Let us find out how many biscuits make up one fifth first.”
Step 1:

Step 3:
Amira: “Let us use our common sense to check our thoughts.”
Half of the packet would be exactly 10 biscuits. The fraction 3/5 is slightly more than a half. This means more than 10 biscuits were eaten. Use that fact to rule out some of the answers.
✅ Perfect, 8 biscuits left. The crumbs don’t lie, but the culprit might!

The Glitter Trail
The glitter trail measured 4 metres
❌ 2 metres would mean a 1:1 ratio, not 3:1.
Jack: “We need to make sure all our measurements speak the same language.”
Step 1:
Step 2:
Step 3:
Lucy: “Look for the relationship between the parts.”
For every section of glitter, there are three parts of silver and one part of gold. This means the entire trail is made of four equal parts in total. How can you simply divide the grand total of 4 metres by 4 to find the size of one part?
❌ 3 metres would mean almost all silver glitter missing, which isn’t right.
Jack: “We need to make sure all our measurements speak the same language.”

Lucy: “Look for the relationship between the parts.”
For every section of glitter, there are three parts of silver and one part of gold. This means the entire trail is made of four equal parts in total. How can you simply divide the grand total of 4 metres by 4 to find the size of one part?
❌ 4 metres means only gold, no silver at all.

✅ You are on the right track!
The Locker Combination
The detectives suspected someone had hidden the painting in a cloakroom locker. The lock opened with a 3-digit code, and the clues scribbled on the wall read:
“This reminds me of algebra,” Emma said quietly, studying the pattern.
❌ Hmmm, that doesn’t work.
Emma: “Let us set up a system to crack this code.”
Step 1:
Step 2:
Step 3:
Amira: “Trial and error is a perfectly valid mathematical strategy.”
Start by guessing the first digit. What if the first digit is 2? The middle would be 4, and the last would be 5. Do those add up to 15? Adjust your starting number upwards until the total matches perfectly.
✅ Remarkable codebreaking ability!
The Assembly Graph
The assembly chart looked like a mystery all on its own. Of 180 pupils, just 135 had arrived, leaving a crowd of invisible students lurking somewhere in the shadows. If these absentees were scattered evenly across the five classes, how many class-sized escape artists would be in each class?
❌ 7 × 5 = 35, too few.
Lucy: “Let us break this into two simple mental steps.”
Step 1:
Step 2:
Step 3:
Oliver: “Picture the missing pupils as a block.”
Imagine a bar model showing 180 total pupils. One part is 135. Find the value of the missing part. Now draw 5 empty boxes underneath. How do you split that missing part into the 5 boxes evenly?
❌ 8 × 5 = 40, too few.

The Final Twist
The detectives gathered in the Year 6 cloakroom, eyes darting from the empty wall hook to the glitter-sprinkled floor. Jack leaned down and picked up a few stray custard cream crumbs.
Jack:
Lucy:
Emma:
Oliver:
The detectives exchanged knowing glances.
Lucy: So all the adults are out
Jack pointed to the glitter trail: “It leads straight to a locker
Emma:
Oliver:
Lucy: “So the glitter, the biscuits, the locker, the code, and the absentees… it all points to one person.”
Now, the most important question is …
❌ Mr Tippet (art teacher): He couldn’t have stolen the painting, as he faints if anyone so much as sneezes near a carpet, let alone pulls off a heist.
❌ Mrs Crumb (caretaker): She wasn’t guilty. Her biggest crime that day was waging war against a particularly stubborn mop bucket.
❌ Mr Pike (headteacher): He wasn’t the thief. He was too busy muttering about “cursed paintings” and hiding behind his office blinds.
They turned to face the culprit – Danny, who was nervously trying to hide a faint grin.
Jack: “Danny, it’s you!
Danny: “Okay, okay, I admit it! I thought it would be funny… I didn’t mean for the whole school to panic.”
The detectives laughed in relief. “Only Danny,” sighed Lucy. “Who else would steal a turnip painting, drop half a biscuit packet in the hall, and leave a glitter trail across the whole school just to make everyone gasp?”
The painting was returned, the mystery solved, and the detectives had enjoyed every absurd, sparkly, custard-stained step of the chase. And we hope you enjoyed it too. 🙂
