First edition. The book is firmly bound in green cloth boards lettered and decorated in light green to spine and front board, the extremities are slightly bumped and rubbed and the boards a little bowed. The text block is lightly toned with minor spotting. The dust jacket is the original, it is a little rubbed, nicked and grubby but overall it is an unusually bright example. The book is preserved in a custom made chemise and slipcase. The third adventure featuring Professor Challenger, Lord John Roxton and the journalist, Edward Malone, in an adventure that sees them investigating the existence of life after death. Uncommon in such excellent condition.
