'That's a totally different thing,' said Prieme impatiently; 'then it was only one Swede, and it didn't much matter whether he lived or died. But, boy, if many thousand innocent people are about to perish through one man's knavish trick, ought we not to bring the traitor to justice, ay, though he be father, brother, or son? Look at that dear, good woman, your blind mother! Do you want the Swedes to get in and slaughter her? Are you going to let sixty thousand brave men and women perish, and all our toils and struggles be in vain, just to save one villain from the punishment he deserves?'

'Oh, dear me, whatever shall I do? No, indeed, neighbour Prieme,' said Conrad, in great distress. 'But I'm sure I don't know anything at all about my step-father, except that he'—

'Jüchziger is to come instantly to the Burgomaster,' cried a well-known voice, as the door of the living-room opened, and Roller's bandaged head appeared.

'Yes,' said Prieme in a tone of vexation; 'but the bird has flown, and even now I am busy with his brood. Good woman, cannot you give us some information about your husband?'

'Nothing more,' said Mistress Jüchziger, 'than this, that about an hour ago, while Conrad was gone out of the room, my husband was burning something over the lamp. At first I thought it was only tinder, but there was a sudden noise at the room door, and I fancied I heard my husband hastily crumple up a piece of paper, and throw it either under the window-seat or the cupboard. No one entered as my husband seemed to expect; it was only the cat scratching to be let in.'

'You here!' cried Roller to his dog, which had followed him in, and which now went open-mouthed at the cat, she in her turn retiring under the cupboard, a safe refuge into which the dog could not follow her. 'You here!' said Roller again. 'Get out, Turk!'

Turk had planted himself in front of the cupboard, and was now scratching vigorously with his fore-paws at the unhappy cat's hiding-place. As he did so, he threw out a ball of paper rolled closely together, which the sharp-sighted Prieme instantly picked up and unfolded. It was a fragment of a written sheet, partly burned, and in several places quite illegible.

In a state of the highest excitement, Prieme brought the paper into the lamp-light, and with trembling lips read as follows:—

'To rouse the prisoners singly and without being observed … in conjunction with forty of our bravest soldiers under Captain … into the city … as soon as the petard sent herewith has done its work and the tower is destroyed, the corps held in readiness will make an attack on that point, which you will powerfully support with the men placed under your guidance. At the same time the storm on all the other positions … The fifty ducats required to make up the sum named shall'—

A loud report sounding at this moment through the air, and overpowering the noise of the artillery, cut short the further reading of the paper.
