He would not betray her, but he determined to watch her narrowly.
Accordingly, when she went forth one morning in company with her younger sister (a little girl of some five years old), he made an excuse to follow them, and, keeping within sight, perceived them enter Saint Paul's Cathedral, the mid aisle of which was then converted into a public walk, and generally thronged with town gallants, bullies, bona-robas, cut-purses, and rogues of every description.

In short, it was the haunt of the worst of characters of the metropolis.

When, therefore, Amabel entered this structure, Leonard felt certain it was to meet her lover.

Rushing forward, he saw her take her course through the crowd, and attract general attention from her loveliness--but he nowhere discerned Maurice Wyvil.
Suddenly, however, she struck off to the right, and halted near one of the pillars, and the apprentice, advancing, detected his rival behind it.

He was whispering a few words in her ear, unperceived by her sister.
Maddened by the sight, Leonard hurried towards them, but before he could reach the spot Wyvil was gone, and Amabel, though greatly confused, looked at the same time so indignant, that he almost regretted his precipitation.
"You will, of course, make known to my father what you have just seen ?" she said in a low tone.
"If you will promise not to meet that gallant again without my knowledge, I will not," replied Leonard.
After a moment's reflection, Amabel gave the required promise, and they returned to Wood-street together.
