This sounded serious!
I had never heard of Polly Polyp--but I knew only too well of the infamous Crawly Crustacean!
He was a big, ugly lobster with only one claw--his left claw--which had grown to enormous size--as sometimes happens to the whole race of lobsters!
But in Crawly's case, this deformity had soured his temper and finally driven him to a life of crime.
And now--from the evidence of this message in a bottle, he had stooped to kidnapping!
Poor Polly Polyp!
I had to find out where Crawly was quickly! And my best source of underworld information was that sleazy character, Barnacle Bill!
And I knew very well where to find him!
