What is the main conflict in Loitering with Intent by Muriel Spark?

After Fleur's submission of her manuscript, a series of strange occurrences follow that lead Fleur to believe that her manuscript has been stolen and used for purposes for which it was not intended. She soon finds out that her suspicions are correct and that Sir Quentin has not only obtained and read a copy of the manuscript, but has been using passages from it to add to the memoirs of clients at the Autobiographical Association.
