Below: I found a list of payments authors received for allowing their works to be serialized

If the list can be trusted, HRH received £1500 for JOAN HASTE, but only £200 for AYESHA, and $800 for MORNING STAR

AYESHA was also serialized in THE WINDSOR MAGAZINE, and it would be interesting to know what payment HRH received

Below: 5 receipts issued by The Perry Mason Company to HRH acknowledging what was paid to HRH for articles he wrote
