Mark and shark: detectiving and stuff - John Dougherty

Meet Mark (a boy) and Shark (a shark) - they're experts(ish) in detectiving and stuff.

When an enormous polar bear asks for their help with some stuff for her ice cream business, it sounds a little bit dull - but little do they realize that they'll end up doing more detectiving than they bargained for! With wild humour and hilarious illustrations, it's non-stop fun from beginning to end.
