What was the content of the letter written by the peddler to Edla?

The peddler thanked Edla for all her kindness and for treating him as a captain, which raised him to the status of a captain. He thanked her for bringing about a change in him, reforming him, offering him true friendship and high regard. He also gifted a rattrap as a Christmas present to Edla from a rat who would have been caught in the world’s rattrap, if he had not been raised to the status of captain. He also requested her to return the crofter’s money that he had stolen.
