"Dark words, Galen!"
"Dark deeds!" the old man answered. "And a path to be chosen in darkness! Shall I poison the man whom I taught as a boy? Shall I refuse, and be drowned in the sewer by Marcia's slaves? Shall I betray my friends to save my own old carcass? Shall I run away and hide, at my age, and live hounded by my own thoughts, fearful of my shadow, eating charity from peasants? I can easily say no to all those things. What then? It is not what a man does not, but what he does that makes him or unmakes him. There is nothing left but subtlety, my Sextus. What will you do? Go and do it now. Tomorrow may be too late."
Sextus shrugged his shoulders, baffled and irritated. He had always looked to Galen for advice in a predicament. It was Galen, in fact, who had kept him from playing much more than the part of a spy-listening, talking, suggesting, but forever doing nothing violent.
"You know as well as I do, there is nothing ready," he retorted. "Long ago I could have had a thousand armed men waiting for a moment such as this to rally behind Pertinax. But I listened to you—"
"And are accordingly alive, not crucified!" said Galen. "The praetorian guard is well able to slaughter any thousand men, to uphold Commodus or to put Pertinax in the place of Commodus. Your thousand men would only decorate a thousand gibbets, whether Pertinax should win or lose. If he should win, and become Caesar, he would have to make them an example of his love of law and order, proving his impartiality by blaming them for what he never invited them to do. For mark this: Pertinax has never named himself as Commodus' successor. I warn you: there is far less safety for his friends than for his enemies, unless he, with his own hand, strikes the blow that makes him emperor."
"If Marcia should do it—?"
"That would be the end of Marcia."
"If I should do it?"
"That would be the end of you, my Sextus."
"Let us say farewell, then, Galen! This right hand shall do it. It will save my friends. It will provide a culprit on whom Pertinax may lay the blame. He will ascend the throne unguilty of his predecessor's blood—"
