As was customary, Mrs Stevenson would read the draft and offer her criticisms in the margins. Louis was confined to bed at the time from a haemorrhage. Therefore, she left her comments with the manuscript and Louis in the toilet. She said that in effect the story was really an allegory, but Louis was writing it as a story. After a while Louis called her back into the bedroom and pointed to a pile of ashes: he had burnt the manuscript in fear that he would try to salvage it, and in the process forced himself to start again from nothing, writing an allegorical story as she had suggested. Scholars debate whether he really burnt his manuscript; there is no direct factual evidence for the burning, but it remains an integral part of the history of the novella.
Stevenson re-wrote the story in three to six days. A number of later biographers have alleged that Stevenson was on drugs during the frantic re-write; for example, William Gray's revisionist history A Literary Life (2004) said he used cocaine, while other biographers said he used ergot.[9] However, the standard history, according to the accounts of his wife and son (and himself), says he was bed-ridden and sick while writing it. According to Osbourne, "The mere physical feat was tremendous and, instead of harming him, it roused and cheered him inexpressibly". He continued to refine the work for four to six weeks after the initial re-write. The novella was written in the southern English sea side town of Bournemouth, where Stevenson had moved due to ill health, in order to benefit from its sea air and warmer southern climate.
