There is many a mystery, of which no word has ever been breathed abroad, hidden away under the marble tombs and flower-decked graves of our great cemeteries.

It has happened that a belated traveller, passing the gates of a cemetery in the hours of darkness, has been startled to see among the distant tombs dim lanterns moving here and there. He has probably hurried away, for not many of us are brave enough to overcome the dread of watching a city of the dead after nightfall.

But he has only seen the preparations for the carrying out of the Home Secretary's order for exhumation. An unsuspected crime is believed to have been hidden away in the graveyard.

Something has come to light which has aroused suspicion, and the proverb that "Murder will out" is about to be justified again.

But there are mysteries of crime which lie in the cemeteries never to be brought to the light of day, and there are mysteries of romance lying there unsuspected too.

The allegations in the famous Druce-Portland mystery startled England. They remain allegations, for the Home Secretary has persistently refused to allow the truth of the tomb to be laid bare. But there are empty coffins in family vaults and under splendid monuments, and there are coffins tenanted by men and women who never bore the name that is upon the coffin-plate.

The sham funeral always conceals a mystery which is not likely to be revealed, for those who have arranged it have the best of reasons for keeping lifelong silence.

The sham or substituted burial takes place, as a rule, in connection with insurance frauds.

I have given chapter and verse in a former chapter with regard to the substitution of bodies, and quoted from the evidence given before a Parliamentary Commission to prove that fraud under our present system of death certification is not only possible but quite easy of accomplishment.

Here is a case which will prove to the doubting reader how simple it is to bury a man with all formalities satisfied, while he is still alive.
