When Johannes went into his little room that evening, as he looked at the moon-shadows of the ivy leaves which stole across the brick floor, he fancied he heard a tap at the window. He thought it was an ivy leaf shaken by the wind. But it was such a distinct knocking, three taps each time, that Johannes softly opened the window and cautiously peeped out. The ivy against the wall glistened in the blue gleam—the dark world below was full of mystery; there were hollows and caves, where the moon lighted up small blue sparks, which made the darkness behind seem deeper still. After staring for a long time into the marvels of the shadow-world, Johannes discerned the form of a tiny mannikin, close to the window, screened by a large ivy leaf. He at once recognised Wistik by his large wondering eyes and uplifted eyebrows. The moon had set a spark of light on the tip of Wistik's long nose.
'Have you forgotten me, Johannes? Why do you never think of me? It is the right time of year. Have you asked Robin Redbreast to show you the way?'
'Oh, Wistik, why should I ask? I have all I can wish for. I have Robinetta.'
'But that cannot last long. And you might be happier still—and certainly Robinetta might. And is the little key to lie there? Only think how splendid it would be if you two were to find the Book! Ask Robin Redbreast about it, and I will help as far as I can.'
'I can ask about it at any rate,' said Johannes.
Wistik nodded, and nimbly scrambled down to the ground; and Johannes looked at the deep shadows and the shining ivy leaves for a long time before he went to bed.
Next day he asked the Redbreast whether he knew the way to the golden chest. Robinetta listened in surprise. Johannes saw the Robin nod his head and give a side-glance at Robinetta.
'Not here! not here!' piped the little bird.
'What are you asking, Johannes?' said Robinetta.
'Do you know anything about it, Robinetta? Do you know where it is to be found? Are you not waiting for the little golden key?'
