When they discover that not only has Mike paid for his new canary-coloured pullover
with a forged £5 note but that has also received a forged note in change, Jim
and Birdie are not slow to realise that here is another case for 'Dance and Co Detectives'.

fit in the picture ?|
As usual of course they underestimate the powers of Sergeant Gribbon and find that he has an answer for everything.
