Two Sought Adventure

No book-club edition is documented. The reprint tell here is internal rather than external: the gray-cloth (c. 1959) and red-boards (c. 1960) bindings are later issues of the same 1957 sheets, not separate printings — they are the common trap precisely because text block, jacket and imprint are otherwise identical to the first binding. Only black boards lettered in red on the spine represent the first binding.
