We have already discussed the substantial and excellent biography of Fr Doyle entitled Worshipper and Worshipped by Carole Hope. You may read a review of it here http://fatherdoyle.com/2014/02/13/book-review-of-worshipper-and-worshipped/ Amazon was out of stock for a few days they now have some stock, so hurry up and place an order! You can find a link on the right hand side of the page.
The other exciting news is that the Catholic Truth Society have produced a new booklet about Fr Doyle entitled Fr Willie Doyle & World War I, written by K.V. Turley. It is excellent. You can order copies here: http://www.ctsbooks.org/fr-willie-doyle-and-world-war-iI will leave a permanent link to it on the right hand side of the page, and will write a more extensive review of it in the coming days.
Finally, I shall be giving a lecture on Fr Doyle in Lismullin Conference Centre near Navan, County Meath, Ireland on Thursday March 20 at 8pm. Details here: http://www.lismullin.org/component/jdownloads/finish/6/52?Itemid=0
