On the world of Moth was the boy Flinx an otherwise unprepossessing orphan who had lived by his wits ever since he could remember. He had two special advantages. One was his pet, Pip, who was death to anyone who threatened its master. The other was an ability to sense other people's thoughts. When he told a couple of men how to find a third as part of his stage act, he's gratified to receive a hundred credits but when he disturbed a fatal attack a few minutes later, he's intrigued to find the attackers were none other than his erstwhile customers! A chance meeting in a pub led to adventures in the depths of space that would lead to a burgeoning set of opportunities for the boy.
This was the first book to feature young Flinx, one of Alan Dean Foster's more enduring characters, in his far future sequence, 'the Humans Commonwealth'. Flinx and his colleagues had uncovered the secret of a weapon from the mysterious Tar-Aiym built in the final days of their rule. No one could be sure what the purpose of the mysterious Krang was. Ancient rumour claimed the Krang as the ultimate musical instrument or the ultimate weapon. No way to tell as not all Tse-Mallory's or Truzenzuzex's long scientific knowledge could make it work, nor did Malaika's devious business mind. Nor did Flinx's unformed mental powers suffice.
I like the background of the Humanx Commonwealth and there's a lot to like in this book, though there's also a lot to dislike. The worst character in the book is Malaika who would be OK if one had never met Poul Anderson's Nicholas Van Rijn (like me whe I'd first read this). In comparison, Malaika comes over as fairly one dimensional.
