The sacristan's face and manner changed at once. His small eyes were suddenly full of intelligence, his mouth expanded in a friendly smile, and his snub nose seemed to draw itself to a point like the muzzle of a hound on a scent.

'Why did you not say that at once?' he asked. 'Rustan left the church a quarter of an hour before you came, but he is not far away. Do you see the entrance to the lane down there?'

He pointed towards the place.

'Yes,' said Omobono, 'by the corner.'

'Yes. Go into that lane. Take the first turn to the left, and then the second to the right again. Before you have gone far you will find Rustan walking up and down.'

'Walking up and down?' repeated Omobono, surprised that the Bokharian should select for his afternoon stroll such a place as one might expect to find in the direction indicated.

'Yes.' The sacristan grinned and winked at the Venetian clerk in a knowing way. 'He is a devout man. When he has said his prayers he walks up and down in that little lane.'

The man laughed audibly, but immediately looked behind him to see whether any one coming from within the church had heard him, for he considered himself a clerical character. Omobono thanked him politely.

'It is nothing,' answered the sacristan. 'A mere direction—what is it? If I had asked you for your purse and cloak by four toes and five toes, I am quite sure that you would have given me both.'

'Of course,' replied Omobono nervously, seeing that the reply was evidently expected of him. 'Of course I would. And so, good-day, my friend.'
