Of course both were busy with their preparations for departure, and she paid but little attention to what he said, as it was upon a subject she knew nothing of, and yet her woman's wit and insight told her that her lover was engaged in something of a mysterious nature, and she hailed with delight the prospect of getting out of Germany and back to America.

The following day the whole world was startled and monarchs trembled at a dynamite explosion in St. Petersburg.

The Czar Alexander was riding along in a carriage, closely guarded by soldiers and mounted police, when, without an instant's warning, a cartridge exploded directly under his carriage, killing everybody and everything within a radius of fifty yards, producing the greatest havoc and devastation.

"Quick–the czar!" cried those who had escaped the terrible explosion.

And a rush was made to the scene of the wreck, where lay mangled horses and human beings, and out of that chaos of desolation they dragged the mangled body of the Czar of all the Russias!

Panic and consternation seized St. Petersburg, seized all Russia–the whole world, in fact.

Instant search was made for those who perpetrated the terrible deed.

One or two suspected individuals were put to the sword without judge or jury, yet they were innocent of the deed.

Detectives and secret service officers took possession of the spot and examined everything–every shovelful of snow even.

Out of the ruin wrought by the terrific explosion one of the officers pulled a small metal plate, crooked and bent by the concussion.
