And so it came to pass that just as Birbal had almost given up hope of coming even upon a trace of the lost diamond; when, thrown back upon himself, he was meditating the possibility of a private audience with the Beneficent Ladies, and a complete throwing of himself upon their mercy, he received a message to come down without delay to the Hall of Labour. He found William Leedes attempting to make out the meaning of a little scented note in a brocaded bag, which had been left for him at the outside door.

"A woman's writing for sure," said Birbal quickly at his first glance. "See how the curves are clipped showing lack of decision." He read the first words--"Ye Gods!" he muttered; so ran hastily through the few lines which appointed a place for the due restoration of the missing gem.

Then he refolded the letter, replaced it in its covering without a word, and stood silent, all the confident vitality gone from face and figure. Suddenly he sniffed at the brocaded bag. "Aye! violets!" he murmured. "The Lady Umm Kulsum's favourite flower! By heaven and earth, Birbal! thou art a fool!" He flung his arms out so recklessly that it seemed as if he would strike himself. "'Tis my mistake after all, sir jeweller! I must have confused the true and the false, for this is from the palace." he said bitterly, "and all my searchings, my chase after that vanishing quantity the harlot Siyah Yamin hath been lost time! I am a fool!"

It was a few minutes ere his quick brain had regained sufficient self-confidence to work; but then it worked rapidly. At nine o'clock--it was now six--by the large flat stone at the Anup tank, not only William Leedes must be in evidence, but he, Birbal, and a strong guard of deaf and dumb slaves must be concealed close by so as to prevent any possibility of treachery. For Birbal did not forget Akbar's curious challenge to his courtiers that day, or that the safe conduct given to the Englishman was a promise which an assassin's dagger might easily break. Ralph Fitch and John Newbery were too far away to be points of attack, but William Leedes must be guarded. Aye! and endless other possibilities must be foreseen, and precautions taken against defeat. For in this case defeat would mean a change in the King's whole line of policy. It is true that it would also, in all probability, mean his acceptance of practical politics and so bring him round to Birbal's point of view--namely that Kingship must follow certain definite and familiar lines; but Birbal's wholehearted love of his master could not brook defeat for him. What action he took must be free, not forced.

So in the interval between the time of receiving the notice of appointment and the appointment itself Birbal set seriously to work in consultation with Abulfazl.

"The hounds of hell will scour heaven and earth to find some pitiful failure," he said finally, almost grinding his teeth with impotent regret. "Lo! Shaikh-jee! What ails the King at times to give such handle to his enemies?"

"It is his sense of strength," replied Abulfazl calmly. "He feels like a God, and of a truth he is one." The Prime Minister's flattery had grown to be part of himself; he really thought of Akbar as he wrote about him.

"Perchance!" growled Birbal, "but he lives among men, and men know how to trick their gods. I can think of no more promises; if thou dost, guard against failure, for my leisure may be scant."

As he made his way to the appointment, he told himself that it might be scant indeed; since, somehow, he must recover the diamond that night. Despite his unbelief, his clear wit, his critical outlook on all things, he could not escape from the feeling that the best safeguard to his master would be the repossession of the lucky stone. Yes! he must recover it.

The night was dark, dark enough to favour the posting of men unseen in the shadow of the trees to the left of the big flat stone. So dark that even the still levels of the tank lay unrevealed, save here and there, where a feeble oil rushlight shone on the shore showing the little platter of food for the dead on which it stood, the fading chaplet of flowers twined around the offering.
