With that announcement out of the way, today's episode is equal parts grand, intrepid adventure and terrifying horror story.

But there was one itch that kept nagging at the compulsive brains of the great and the good - and that was the Arctic.

The theory was sound:

Logically, from the spherical shape of the globe, there should be some kind of route from Europe that went due north west across the Atlantic, between the coasts of Greenland and Canada.

Then you would head sharply west at Baffin Bay and travel “over” the seas off the northern coast of Canada before finally heading south again into the clear waters of the Pacific.

From there it ought to be plain sailing to Japan, China and the rich trading zones of the Asian continent.

But the mission remained alluring for a few reasons:

So the stakes were high.
