Somewhere deep beneath the wild seas of the southern Indian Ocean, perhaps in the eerie underwater canyons of Broken Ridge along the Seventh Arc satellite band, lies the answer to the world’s greatest aviation mystery.

Why, on the night of 8 March 2014, did Malaysia Airlines Flight MH370 suddenly U-turn, zig-zag up the Straits of Malacca, then vanish with 239 souls on board?

Was it an elaborate murder-suicide by a rogue pilot? A terrible accident such as onboard fire, rapid decompression or systems failure? A terrorist hijacking gone wrong? Or something else entirely?

Award-winning journalist Ean Higgins has led the world media’s coverage of this incredible saga and draws on years of interviews with aviation experts, victims’ families, air crash investigators and professional hunters across land, sea and sky to dissect the riddle of MH370’s fate.
