Emil Gluck, having disposed of his immediate enemies, now sought a wider field, though his enmity for newspaper men and for the police remained always active.  The royalties on his ignition device for gasolene-engines had mounted up while he lay in prison, and year by year the earning power of his invention increased.  He was independent, able to travel wherever he willed over the earth and to glut his monstrous appetite for revenge.  He had become a monomaniac and an anarchist—­not a philosophic anarchist, merely, but a violent anarchist.  Perhaps the word is misused, and he is better described as a nihilist, or an annihilist.  It is known that he affiliated with none of the groups of terrorists.  He operated wholly alone, but he created a thousandfold more terror and achieved a thousandfold more destruction than all the terrorist groups added together.

He signalized his departure from California by blowing up Fort Mason.  In his confession he spoke of it as a little experiment—­he was merely trying his hand.  For eight years he wandered over the earth, a mysterious terror, destroying property to the tune of hundreds of millions of dollars, and destroying countless lives.  One good result of his awful deeds was the destruction he wrought among the terrorists themselves.  Every time he did anything the terrorists in the vicinity were gathered in by the police dragnet, and many of them were executed.  Seventeen were executed at Rome alone, following the assassination of the Italian King.

Perhaps the most world-amazing achievement of his was the assassination of the King and Queen of Portugal.  It was their wedding day.  All possible precautions had been taken against the terrorists, and the way from the cathedral, through Lisbon’s streets, was double-banked with troops, while a squad of two hundred mounted troopers surrounded the carriage.  Suddenly the amazing thing happened.  The automatic rifles of the troopers began to go off, as well as the rifles, in the immediate vicinity, of the double-banked infantry.  In the excitement the muzzles of the exploding rifles were turned in all directions.  The slaughter was terrible—­horses, troops, spectators, and the King and Queen, were riddled with bullets.  To complicate the affair, in different parts of the crowd behind the foot-soldiers, two terrorists had bombs explode on their persons.  These bombs they had intended to throw if they got the opportunity.  But who was to know this?  The frightful havoc wrought by the bursting bombs but added to the confusion; it was considered part of the general attack.
