In the green light the Indian’s sombre eyes stared round the group of dim faces.

“Did I not say,” he answered, “that there was power in the box? But in the name of that power—unknown to you—I warn you: Do not touch those pearls till the light has burned low in the brazier. If you do they will disappear—never to return. Watch, but do not touch!”

Slowly he backed towards the window, unperceived in the general excitement; and Hugh dodged rapidly towards the car. It struck him that the séance was over, and he just had time to see Lakington snatch something which appeared to have been let down by a string from above, before turning into the bushes and racing for the car. As it was he was only a second or two in front of the other, and the last vision he had through a break in the trees, before they were spinning smoothly down the deserted road, was an open window in Laidley Towers from which dense volumes of vapour poured steadily out. Of the house party behind, waiting for the light to burn low in the brazier, he could see no sign through the opaque wall of green fog.

It took five minutes, so he gathered afterwards from a member of the house party, before the light had burned sufficiently low for the Duchess to consider it safe to touch the pearls. In various stages of asphyxiation the assembled guests had peered at the box, while the cynical comments of the men were rightly treated by the ladies with the contempt they deserved. Was the necklace not there, wrapped in its gold and silver tissue, where a few minutes before there had been nothing?

“Some trick of that beastly light,” remarked the Duke peevishly. “For heaven’s sake throw the dam’ thing out of the window.”

“Don’t be a fool, John,” retorted his spouse. “If you could do this sort of thing, the House of Lords might be some use to somebody.”

And when two minutes later they stared horror-struck at a row of ordinary marbles laboriously unwrapped from a piece of gold and silver tissue, the Duke’s pungent agreement with his wife’s sentiment passed uncontradicted. In fact, it is to be understood that over the scene which followed it was best to draw a decent veil.

Drummond, hunched low over the wheel, in his endeavour to conceal his identity from the man behind, knew nothing of that at the time. Every nerve was centred on eluding the pursuit he thought was a certainty; for the thought of Lakington, when everything was prepared for his reception, being snatched from his clutches even by the majesty of the law was more than he could bear. And for much the same reason he did not want to have to deal with him until The Elms was reached; the staging there was so much more effective.

But Lakington was far too busy to bother with the chauffeur.
