This problem was set in Peter Parley's Annual, 1877, but I fear that
they are no longer available to provide the answer:

I'm not sure but, in connection with the Children's annuals, it seems
Peter Parley was a pseudonym of George Mogridge; rather than the American
author Samuel Griswold Goodrich who established that pseudonym. However,
both would have been dead by 1877.

It seems a bit of a coincidence that publisher Faber and Faber are now
based at 51 Hatton Garden, London, but they haven't been around long
enough to be involved in this particular publication.

The Hatton Garden safe deposit burglary took place a few doors away in
April 2015. At the time the value of the goods taken was £14 million.

I'm suspecting there isn't a solution to this puzzle, but hope to be
proved wrong. I'm continuing to work on it.
