Wakefield’s Course [PDF ebook] 

Originally published in 1941, Wakefield’s Course begins in the spring of 1939 at Jalna. Renny Whiteoak is keen to sail for Ireland with his small daughter, Adeline, to buy a racehorse, but he’s more eager to see his younger cousins, Finch and Wakefield, who have been living in London. On his arrival in England, Renny becomes entangled in his cousins’ affairs of the heart. This is book 12 of 16 in The Whiteoak Chronicles. It is followed by Return to Jalna.
