Ignorant of the name of Shelley's coadjutor in this discreditable business, Mr. Garnett is at much pains to show, who could not have been the coadjutor, who may not be supposed to have been the coadjutor, and who might have been the coadjutor. Hogg could not have been the coadjutor, because he had not yet made the poet's acquaintance. Tom Medwin was not the coadjutor. But Mr. Garnett is of opinion that Miss Harriett Grove may have been the coadjutor. 'A more likely coadjutor,' he says, 'would be Harriet Grove, Shelley's cousin, and the object of his first attachment, who is said to have aided him in the composition of his first romance, _Zastrozzi_.' It is strange that so exemplary a Shelleyan expert as Mr. Garnett dealt thus respectfully with what Shelley told Medwin, or Medwin imagined himself to have been told by Shelley, about Harriett Grove's part in the composition of _Zastrozzi_. There is no more truth in the fable that Harriett Grove wrote some of the chapters of _Zastrozzi_, than there is in the fable that she was the Harriett of the Dedicatory Prelude to _Queen Mab_. Possibly Shelley saw his pretty cousin in her Wiltshire home, when he went from Brentford to Fern for the Easter holidays, in the company of her Harrovian brothers. Probably the cousins saw one another on other occasions, when they were small children; but when they met at Field Place in the summer of 1810, they came together as new acquaintances. There is decent, though not conclusive, evidence that they had never looked on each other before that summer. It is certain that their brief intimacy, attended with innocent flirtation and cousinly correspondence, was an affair of the later six months of 1810:--that _Zastrozzi_ had been written to the last line, sent to Messrs. Longman and Co., declined by those publishers, sent to Messrs. Wilkie and Robinson, printed by them, and almost, if not actually published, before the dawn of that brief intimacy. So much for what has been written about Harriett Grove's participation in the authorship of the earlier of Shelley's inexpressibly ludicrous novels.
