We did understand. We were watched as if he assumed that we were on the alert for a chance of escape, as we were. On night marches a leathern thong was knotted about my waist and the ends knotted similarly about the waists of the man before me and the man behind me. Agathemer was made secure in a like fashion. When he lay down to sleep, after he had composed himself to rest, a blanket was spread over him and a burly ruffian lay down on either side of him, the edges of the blanket under them. I slept similarly guarded. On day marches Caburus kept Agathemer close to him; I was never out of sight of Maternus. Somewhere in the Etrurian hills north of Arretium I overheard part of a conversation between Maternus and Caburus. They were talking of me and Agathemer. "You cannot be sure," said Maternus. "By every rule of reason Hedulio ought to hate Commodus consumedly. But loyalty is so inbred in senators and men of equestrian rank, in all the Roman nobility, that he may have a soft place in his heart for him, after all. Instead of doing his best to help us kill him he might try to shield him, at a pinch." "Just what I have been thinking," said Caburus. "I am half in doubt about this enterprise, even now. Agathemer may after all, try to fool me and to shield Commodus, by pointing out some other man to me, at the crucial moment." "If you suspect him of anything of the kind," said Maternus gently, "just drive your dirk good and far into him and be done with him. I'll be on the lookout for any hanky-panky from Hedulio. If I see the wrong look in his eye or the wrong expression on his face I'll make a quick end of him. I'll tolerate no treachery after oath given and oath taken." It may easily be imagined how nervous and uncomfortable I felt after hearing this mild, soft-voiced utterance. My anxiety was accentuated within an hour. Just as I, like the other members of the band, was composing myself to sleep, I heard high words, raised voices, threats, an oath and a yell. With the rest I rushed towards the sounds. There, with the rest, I saw Caulonius Pelops in the agonies of death, a dagger in his heart. One of our Spanish associates had momentarily lost his temper. Maternus, calm and unruffled, mildly inquired the causes of the quarrel, affirmed his belief in the Spaniard's account, absolved him of all blame and ordered Pelops buried. Then, as if nothing happened, we all composed ourselves to sleep. I did not sleep much. Evidently, stabbing on small provocation was taken as a matter of course among my present comrades.
