they reach the control center, the computer starts a self-destruct sequence—a final option to keep the ship from being "stolen". Just in time, Jason's Pyrran lover, Meta, discovers the correct codeword, canceling the self-destruct. It turns out to have been a simple five-letter word in Esperanto: "Haltu" or, "Stop". This short story was featured in Astounding: The John W. Campbell Memorial Anthology which was published after the death of the famed, influential editor. Return to Deathworld The Return to Deathworld series is a collaboration between Harry Harrison and Russian authors Ant Skalandis and Mikhail Akhmanov and has never been published in English. The exact share of Harrison's participation is unclear, as Skalandis has also written several sequels to late Edmond Hamilton's books, and they were published in Russian under both their names.

The second part of Return to Deathworld describes Jason's adventures at the galactic core, strangely mirroring the ancient myth of the Argonauts (including the fact that the hero is named Jason and the battleship's new name is Argo). In fact, Jason recognizes the parallel and attempts to alter the outcome. In Deathworld vs. Filibusters, the remains of the defeated armada (mentioned in "The Mothballed Spaceship") turn to piracy under the leadership of one Henry Morgan. Jason dinAlt is hired by the same casino he won a fortune from at the start of the series to steal back the money Morgan took from the casino. Jason's plan fails when he and Meta are captured by Morgan's men and taken to their hidden
