Mathique
Detective Marlowe Pickle
the dampest detective in town
A soggy green frog in an oversized dripping trench coat and fedora, who narrates his own life like a 1940s film, out loud, to nobody. Dramatic, mostly incompetent, occasionally brilliant.
Year 4 · Ages 8–9
The Soggy Biscuit Detective Agency
Marlowe Pickle, the city’s dampest detective, needs a sharp-eyed partner. Crack cases with column methods, area, angles and time.
The story
Three hopeless detectives run an agency out of a leaking houseboat in Lower Dampington, solving the town’s smallest crimes for biscuit money. Then the silly cases start pointing at the biggest crime in history: someone is stealing Wednesdays. Your child is hired as the agency’s Junior Detective, for the simple reason that they are the only one who can do the sums, and each case turns the maths into the evidence.
How it looks
Bordered comic pages in rich painterly caricature: heavy black linework, warm browns and murky greens, and a permanent drizzle. The practice itself happens on a full-page detective’s notepad.
Meet the cast
Detective Marlowe Pickle and Nib carry the story. Your child is the one who can actually do the maths, so the cast set up every clue and react to every answer, and the solving is left to them.
Nib
in charge of evidence
A hyperactive black crow who eats the evidence, then looks betrayed. His notebook is ninety per cent doodled moustaches, and he shouts "OOH, A CLUE!" at things that are not clues.
The Chief
the boss
A deadpan goldfish in a bowl who says only "blub". The team treats every blub as strategic genius. The running question is whether she actually knows everything.
Mr Tickwell
the town clockkeeper
A fussy, lonely beaver in tweed and a purple bow tie, forever clutching a giant brass winding key and a glowing jar labelled WEDNESDAY. Nobody in Lower Dampington thinks to ask why.
What your child practises in Year 4
The Soggy Biscuit Detective Agency follows the national curriculum for England, in the order a Year 4 class meets it. Every strand below is covered by the story, and Parent HQ reports progress back in exactly these words:
- Number & place value
- Addition & subtraction
- Multiplication & division
- Fractions & decimals
- Measurement
- Shape & angles
- Position & direction
- Statistics
129 story missions in all, plus four boss gates: mixed-review checkpoints that have to be passed before the story moves on, so a skill is proved rather than assumed.
Start with the assessment, not the story
The free start-of-year assessment comes first: twenty questions, two per topic, dressed as your child’s first mission in this world. It shows you which Year 4 strands are solid and which are not, before they spend a single evening on the wrong thing.
