’I have no alternative but to do so,’ replied Nicholas.
I am sorry to have to do it, upon my word I am very sorry, but you leave me no alternative, Miss Nickleby.’
As poor Mrs Nickleby was cooling—not her heels alone, but her limbs generally at the street corner, Kate had no alternative but to make her known to Miss Knag, who, doing the last new carriage customer at second-hand, acknowledged the introduction with condescending politeness.
When Mrs Nickleby had brought this interesting anecdote to a close, Pyke and Pluck, ever zealous in their patron’s cause, proposed the adjournment of a detachment of the party into the next box; and with so much skill were the preliminaries adjusted, that Kate, despite all she could say or do to the contrary, had no alternative but to suffer herself to be led away by Sir Mulberry Hawk.
There are no more uses of "alternative" in the book.
