I just looked through that whole book and there's nothing like that. There's one photo of Arthur & Leonie sailing and some group and individual portraits--none of which give any indication of a strained relationship.
The Connaughts had a strong relationship and Louise accompanied Arthur on almost all his trips and postings, even when her health began to fail. Daisy wrote that her father would be 'absolutely lost & perfectly miserable' (something Leonie seemed to realize) and that her parents had been 'all sufficient for each other'. This might not have been completely true, obviously Leonie supplied something for both of them, and his biographer acknowledges this, but they were true partners. Noble Frankland wrote that 'Indeed, as it had begun, the marriage had always remained a love match. Prince Arthur felt that the parting would have been unbearable had he not believed that there would, in the future, be a reunion. A few days after the funeral he went down to Bagshot resolved to sleep in his marriage bedroom, but he fuond the house sad and lonely, the rooms cold and forlorn and in the middle of the night he woke to find Louischen's dog curled up on the foot of the bed...life could never again be the same for Prince Arthur, and, to his intimates, he conceded, throughout the rest of his long life, that it never was.'
