As has already been stated, there had been sufficient frost to harden mud into rock. Traces of a scuffle—if a scuffle had taken place—would be recognisable still to an eye that knew precisely where to look for them.
Zita went with nimble feet, a busy brain, and fluttering heart towards the point where the van had been arrested in the mud, and she resolved thence to follow the course she had taken on that eventful night along the bank. On this occasion she walked deliberately where she had previously run, and came after a while to the spot where, according to her calculation, she had slipped into the canal. There she found the post standing up out of the water to which she had clung, close to the bank, with the mortice-hole in it that had looked so like a human eye. This was the only post of the kind she had come across, and this was not more than a hundred yards from the spot where she had grasped Drownlands' foot, had held him, and had heard him scream at her touch.
At this point, some hundred yards beyond the post with the hole in it, she carefully explored the soil. The top of the embankment was indented with hoof-marks, but these might have been made by the gangers' horses, which were constantly driven up and down the embankment. But there was something that satisfied the girl that at this spot a struggle had taken place, for on the land side of the embankment tufts of grass and clods of clay had been torn out and thrown into the drove, and on the water side hoof-marks and a slide in the greasy marl were sealed up by the frost as evidences of a horse having there gone down into the water. These had not been observed by any one else, as no one save Zita had known the exact place where to look for them, and though distinguishable enough when searched for, they were not obtrusively manifest.
Zita had not merely a well-arranged mind, but she was able to prize whatever facts came before her at their true value.
Now, as she walked away from the river towards Prickwillow, she realised that there was strong presumptive evidence that Drownlands had been engaged in a tussle with his enemy, and that he knew how it was that Runham had met his death, even if he were not absolutely his murderer.
As Zita entered the house, she heard the master's voice raised in tones of anger. He was addressing Mrs. Tunkiss, the housekeeper.
'It's all idle excuse—you don't want the trouble of it. I know your ways.'
'I haven't a needle will go through it,' answered Leehanna.
Then Drownlands came out of the kitchen. He was swinging in his hand the tiger-skin that usually in cold or wet weather was slung over his shoulders. His eye lighted on Zita, and his face brightened at once.
