been in contact all during the 1920's, had to turn down his request for a
$2,500 loan at the end of January, 1931, Yardley, in desperation, sat
down to write what was to be the most famous book on cryptology ever
published. He described the composition of it in a letter to Manly in the
spring of 1931:
I hadn't done any real work for so long that I told Bye, my
agent, and the Sat Eve Post that I would need some one else to
write the stuff. I showed a few things to Bye and Costain, the latter
editor of POST, and both told me to go to work myself. I sat for days
before a typewriter, helpless. Oh, I pecked away a bit, and
gradually under the encouragement of Bye I got a bit of confidence.
Then Bobbs Merrill advanced me $1000 on outline. Then there was
a call to rush the book. I began to work in shifts, working a few
hours, sleeping a few hours, going out of my room only to buy
some eggs, bread, coffee and cans of tomatoe juice
