Publisher's Synopsis
Certainly, if ever a man found a guinea when he was looking for a pin, it is my good friend Professor Gibberne. I have heard before of investigators overshooting the mark, but never quite to the extent that he has done. He has really, this time at any rate, without any touch of exaggeration in the phrase, found something to revolutionise human life. And that when he was simply seeking an all-round nervous stimulant to bring languid people up to the stresses of these pushful days. I have tasted the stuff now several times, and I cannot do better than describe the effect the thing had on me. That there are astonishing experiences in store for all in search of new sensations will become apparent enough. Professor Gibberne, as many people know, is my neighbour in Folkestone. Unless my memory plays me a trick, his portrait at various ages has already appeared in The Strand Magazine-think but I am unable to look it up because I have lent that volume to someone who has never sent it back. The reader may, perhaps, recall the high forehead and the singularly long black eyebrows that give such a Mephistophelean touch to his face.
