When all was in readiness, Cleek settled down to the story.  He was the only man left standing, a straight slim figure, full of that controlled power and energy that is so often possessed by a small but perfect machine.  He bowed to the judge with something of the theatrical in his manner, and then rested one hand upon the clerk’s table.

“Now, naturally, you are wanting to hear the story,” he said briskly, “and I’ll make it as brief as possible.  But I warn you there’s a good deal to be told, and afterward there’ll be work for Scotland Yard, more work than perhaps they’ll care about; but that is another story.  To begin with, the jury, my lord, was undoubtedly, from all signs, about to convict the prisoner upon a charge of murder—­a murder of which he was entirely innocent.  You have heard Merriton’s story.  Believe me, every word of it is true—­circumstantial evidence to the contrary notwithstanding.

“In the first place, Dacre Wynne was shot through the temple at the instigation of that man there,” he pointed to Brellier, standing pale and still between two constables, “foully shot, as many others had been similarly done to death, because they had ventured forth across the Fens at night, and were likely to investigate this man’s charming little midnight movements, further than he cared about.  To creatures of his like human life is nothing compared to what it can produce.  Men and women are a means to an end, and that end, the furtherance of his own wealth, his own future.  The epitome of prehistoric selfishness, is it not?  Club the next man that comes along, and steal from his dead body all that he has worked for.  Oh, a pretty sort of a tale this is, I promise you!

“What’s that, my lord?  What has the Frozen Flame to do with all this?  Why, the answer to that is as simple as A.B.C.  The Frozen Flames, or that most natural of phenomena, marsh-gas—­of which I won’t weary you with an explanation—­arose from that part of the Fens where the rotting vegetation was at its worst.  What more natural, then, than that this human fiend should endeavour to shape even this thing to his own ends?  The villagers had always been superstitious of these lights, but their notice had never been particularly called to them before the story of the Frozen Flames had been carefully spread from mouth to mouth by Brellier’s tools.

“Then one man, braver than the rest, ventured forth—­and never came back.  The story gained credence, even with the more educated few.  Another, unwilling to conform to public opinion, did likewise.  And he, too, went into the great unknown.  The list of Brellier’s victims—­supposed, of course, to be burnt up by the Frozen Flames—­grew fairly lengthy in the four years that he has been using them as a screen for his underhanded work.  A guard—­and I’ve seen one of the men myself during a little midnight encounter that I had with him—­went wandering over that part of the district armed with a revolver.  The first sight of a stranger caused him to use his weapon.  Meanwhile, behind the screen of the lights the bank robbers were bringing in their gold by motor and hiding the sacks down in a network of underground passageways that I also discovered—­and traversed.  They ran, by devious ways, both to a field in Saltfleet conveniently near the factory, and by another route up to the back kitchen of Merriton Towers.
