Marlowe tells us about the “routine” doctor’s visit he was required to attend before departure to the Congo, “a simple formality.” Yet a few strange things take place. First of all the doctor, with supressed eagerness, asks if he can measure Marlowe’s cranium. Strange. And upon further questioning, the doctor admits that he never gets to take the “after” measurements. No one ever comes back. Foreboding.
Next, the doctor inquires if there is a history of madness in Marlowe’s family. Suggestive?
And his departing advice to Marlowe? Avoid irritation more than sun exposure. “Above all, keep calm,” he says. Just plain weird!
I think I would have reconsidered. Or at least asked more questions. Thanks for the foreshadowing, Conrad.
