Query: Pretty deep

I'm more of a reader of historical fiction set in contemporary times, preferring novels like "From Here to Eternity" or "The Triumph and the Glory", but Pears' book caught my eye and a friend had read it so I bought a copy and settled into read it. I was captivated by the new experience of a literary mystery, but am not accustomed to working so hard for my entertainment! Still, when all was said and done I have to say I was pleased. Hurrah for "An Instance of the Fingerpost", it has won me over to frowning a bit in concentration while reading.
