London was half empty. Parliament was dissolved and the Members of Parliament had all gone to their country houses, the better to stare at the rain. In London Mr John Murray, the publisher, sat in his house in Albermarle-street. At other times Mr Murray’s rooms were the liveliest in London – full of poets, essayists, reviewers and all the great literary men of the kingdom. But the great literary men of the kingdom had gone to the country. The rain pattered upon the window and the wind moaned in the chimney. Mr Murray heaped more coals upon the fire and then sat down at his desk to begin reading that day’s letters. He picked each letter up and held it close to his left eye (the right being quite blind and useless).

It so happened that on this particular day there were two from Geneva in Swisserland. The first was from Lord Byron complaining of Jonathan Strange and the second was from Strange complaining of Byron. The two men had met at Mr Murray’s house a handful of times, but until now they had never got acquainted. Strange had visited Byron at Geneva a couple of weeks before. The meeting had not been a success.

Strange (who was just now in a mood to place the highest value upon matrimony and all that he had lost in Arabella) was unsettled by Byron’s domestic arrangements. “I found his lordship at his pretty villa upon the shores of the lake. He was not alone. There was another poet called Shelley, Mrs Shelley and another young woman – a girl really – who called herself Mrs Clairmont and whose relationship to the two men I did not understand. If you know, do not tell me. Also present was an odd young man who talked nonsense the entire time – a Mr Polidori.”

Lord Byron, on the other hand, took exception to Strange’s mode of dress. “He wore half-mourning. His wife died at Christmas, did she not? But perhaps he thinks black makes him look more mysterious and wizardly.”

Having taken an immediate dislike to each other, they had progressed smoothly to quarrelling about politics. Strange wrote: “I do not quite know how it happened, but we immediately fell to talking of the battle of Waterloo – an unhappy subject since I am the Duke of Wellington’s magician and they all hate Wellington and idolize Buonaparte. Mrs Clairmont, with all the impertinence of eighteen, asked me if I was not ashamed to be an instrument in the fall of so sublime a man. No, said I.”

Byron wrote: “He is a great partisan for the Duke of W. I hope for your sake, my dear Murray, that his book is more interesting than he is.”

Strange finished: “People have such odd notions about magicians. They wanted me to tell them about vampyres.”
