"And the Tartars cover that in two months? Do they fly?" The fat monk's jowls quivered. Daoud noticed that the front of his white tunic was stained with what appeared to be spots of gravy and wine. Daoud turned to Ana. "Kindly ask the ambassadors to explain to Fra Tomasso how their riders cover such a distance so quickly." After some conversation between Ana and the Tartars, Fra Tomasso had his answer. "The fastest riders and horses in our empire carry messages in relays over the major routes. A message never stops traveling, night and day, until it reaches its destination. At night, runners with torches guide the riders." The Italians looked awed. Daoud felt unimpressed. The Mamelukes also had post riders. They could carry a message from El Kahira to Damascus in four days. "How intelligent!" said Fra Tomasso. "I will warrant we would be better governed here in Europe if we had such a system." The note of admiration in Fra Tomasso's voice made Daoud uneasy. A servant passed, offering cups of wine on a tray. Daoud took a goblet. John and Philip raised the empty cups they held, and Ana refilled them from a pitcher on the table. "Your empire is so vast, is it not," Daoud said to the Tartars through Ana, "that even messages that travel swiftly cannot hold it together?" Philip, the black-bearded Tartar, answered that, smiling. "Fear of the Great Khan holds our empire together," Ana translated. "Is the Great Khan feared even in the lands of Kaidu Khan and Baraka Khan?" Daoud asked, naming the two rebels who did not recognize Hulagu Khan's brother Kublai. He strove for a tone of innocent curiosity. The faces of the two Tartars remained expressionless, but Daoud, schooled by his Hashishiyya masters to notice signs of emotion in the most guarded of men, observed the flush creeping into their brown cheeks, the slight quickening of their breathing, and the twitching of their fingers. Until he asked his disturbing question they had answered Daoud readily, almost casually, as they would any of the contessa's other guests. Now, in silence, they studied him. Waiting for them to finish their inspection, Daoud held out his wine cup to Ana, who filled it from the pitcher on the table. The pitcher was almost empty, and she signaled to a servant to bring another. John Chagan said, and Ana translated, "I do not believe we have had the honor of being presented to you, Messere." Daoud turned to Fra Tomasso, who was following the conversation closely. "Will you be good enough to introduce us, Your Reverence?" Any opportunity to involve himself with the Dominican philosopher could be useful. While Fra Tomasso presented him and Ana translated, Daoud stared at the Tartars with deliberate challenge, draining his wine cup. Philip caught the meaning of the gesture at once, and drank deep from his silver goblet as well. John followed suit.
