It came via the excellent ABE Books network, from a US bookseller and its provenance (it was second hand) was that it originated from a Dominican High School library (City unknown but likely to be NYC).
Like all Fulton Sheen books, it is sound and makes for good reading; I dipped into it at regular intervals until, one day recently, my attention was taken by the old library checkout slip at the back. It carried the names and signatures of the borrowers as well as a list of the return dates but, within the actual library pocket, nestled an old In Memoriam card.
I examined it with a great deal of interest; it carried the name of one Alfred E Overton who died on 28 July 1950. May God have mercy on his soul.
Is it too whimsical to think that this was cry from the depths, asking for prayers to relieve the pains of Purgatory (where, it is said, one second appears as if it were 10 years). I think not. I have prayed for Alfred E Overton ever since and his card has a place in my missal. It took 60 years but the message finally got through.
