Rival ocean divers : $b or, The search for a sunken treasure

Seventeen‑year‑old Dave Fearless inherits a claim to a million‑dollar fortune that went down with the steamship Happy Hour in the middle of the Pacific. With the Hankers family contesting the inheritance, Dave and his father devise a bold scheme to reach the wreck before the wealthy rivals can mount their own expedition. Their plan hinges on a forthcoming government voyage aboard the research ship Swallow, which will carry a new diving bell and the latest deep‑sea sounding equipment.

The story follows the young crew as they plunge into the abyss, confronting crushing pressure, strange luminous creatures, and the ever‑present threat of rival divers determined to seize the treasure. Along the way, scientific marvels of the deep ocean are woven into the suspense, giving listeners a vivid picture of early twentieth‑century marine exploration. The narrative balances daring action with moments of clever problem‑solving, inviting listeners to imagine the rush of a race beneath the waves.
