Challenge "Weakened Handycipher — Part 5"

The Weakened Handycipher challenges serve as an exercise and use an intentionally weakened version of Handycipher. Part 5 is the same as Part 2, but uses an improved version of the cipher. It is ciphertext-only, but you are given some partial information about the key.

The following text was added to the challenge description in order to eliminate an ambiguity:

Remark: The end of each sentence is determined by a letter pair ". " or "? " which
is not part of an ellipsis, an abbreviation, or a quotation attribution.
