This is one of your best stories yet, @bruno-kema. The setting is interesting, the characters have great personalities, and you've added some great adrenaline-pumping suspense.
"And it gets worse." Duke continued, "the passcode is computer generated and it changes every two minutes. If you use a passcode from three minutes ago now, it won't work."
That's awesome. Duke is a great character, full of personality and perfectly offsets Sophia and Samson with his wry tone. Well done!
Thank you very much @jayna. Duke was actually a last minute addition to the story. If hes so good then he might appear in future stories featuring Samson and Sophia.
I am glad you enjoyed the story.
