Therefore, she refused.

Rhodes thereupon flew into a terrible passion and demanded to know the reason for the apparent distrust.

When told that it was not so much a question of distrust as the impossibility of breaking a promise once given, he exclaimed that he would have nothing more to do with the whole business, and started almost immediately afterwards his agitation for the suspension of the Constitution in Cape Colony.

But--and this is an amusing detail to note--Rhodes used every possible effort to obtain possession of the papers he had been allowed to see, going so far as to have the house searched of the person who had refused to allow him to keep the documents--a revenge which was as mean as it was useless, because the papers in question had been at once returned to their rightful owners.
The request made by Rhodes to keep these documents produced a very bad impression on those who had begun to entertain hopes that he might be induced to throw the weight of his personality into the scale of a settlement.

It confirmed the suspicions held by the Afrikander party ever since the Raid.
They say that everyone is afforded once the chance of one's lifetime.
