AUTHOR'S NOTE I Have taken a few liberties
with the current geography of Georgetown University, notably with
respect to the present location of the Institute of Languages and
Linguistics. Moreover, the house on Prospects Street does not
exist, nor does the reception room of the Jesuit residence halls as
I have described it.
The fragment of prose attributed to Lankester Merrin is not my
creation, but is taken from a sermon of John Henry Newman entitled
'The Second Spring'.
