Runners were stationed at posts spaced five _kos _apart along the great road that Akman had built to link Agra to the seaport of Surat. They wore an identifying plume at their head and two bells at their belt, and they gained energy by eating _postibangh_, a mixture of opium and hemp extract. Akman even conceived of lining the sides of the road with white stones so his Mewras could run in darkest midnight without lanterns. There were now some four thousand runners stationed along India's five main arteries.
The only things swifter, Mukarrab Khan had often told himself, are lightning . . . and a blue, white-throated Rath pigeon. A distance requiring a full day for a runner could be covered by a pigeon in one _pahar_, three hours, given good weather. Arangbar kept pigeons all over India, even in Surat--but then so did everyone else at court. Recently, it seemed, everyone was training pigeons.
Next to the date was the seal of Nadir Sharif, prime minister and brother of the queen. Mukarrab Khan knew Nadir Sharif well. A dispatch from Nadir Sharif, though it always reflected the wishes of the Moghul or the queen, could be relied upon to be reasonable. If the Moghul in fury condemned a man over some trivial transgression, Nadir Sharif always forgot to deliver the sentence until the next day, having found that Arangbar often tended to reverse sentences of death when musing in his evening wine cups. This order will be reasonable, Mukarrab Khan told himself, but it will have to be obeyed, eventually.
As always, Mukarrab Khan tried to guess the message before unsealing the two-inch-long silver cap attached to the end of the tube. Probably taxes, late delivery. Or perhaps there's been a discrepancy between the open report filed from my chamber by the wakianavis, the public reportefs, and the private report, which I supposedly do not see, sent directly to the Moghul by the harkaras, the confidential reporters. And if that's the complaint, it will disprove my suspicion that no one in the Imperial chancery ever actually reads the reports. I deliberately inserted a difference of one-half lakh of rupees as reported logged at the mint last month, just to see if they would catch it.
