THE author-investigator follows up his first volume of discoveries by writing about a further 31 air crash sites he has located and identified. In his foreword, Air Vice-Marshal David Hurrell states: “Like all good detective story writers, Chris gives the reader a wealth of detail.

“There are also the traditional red herrings, contradictions and dead ends, all of which he painstakingly sifts through to arrive at logical conclusions which give the reader the same sense of achievement and satisfaction that the author himself clearly enjoys.

“We journey with him, experiencing the highs and lows, the early starts, the muddy fields, the false trails, dashed hopes, and frustrations of every kind. It brings home the sheer scale of his epic investigation in the search for historical truth.”
