What year do you plan to set the novel set in? Things are rather different in 1558 when Elizabeth comes to the throne than in 1568 when Mary QoS arrives expecting help (2 years before the Papal Bull) and that's different from 1587 when Mary is executed following the various conspiracies, and that's different from 1601 with the Essex rising (not a Catholic plot, but closer to a real threat than the others), and all very different again after James come to the throne in 1603, and then again in 1605 after the failed Gunpowder Plot. Tensions ebb and flow, as do alliances between courtiers and states, all of which affects how people behave -- even the weather is an issue some years because of famine and an increasing number of beggars. Fashion change over the years; even the food people are eating.
Anyhow, I've remembered another set of novels set in the relevant period, the Hew Cullen series by Shirley McKay which spans 1579 to 1587. They're set primarily in the Scotland of James VI so might not be what you want, but some action in Queen and Country takes place in England (In flashback, at least) and again involves Mary QoS. The other books I've recommended are good on period detail but these were excellent in that respect, the characters very much of their time, and not C21st people in fancy dress as can happen in historical novels, and the dialogue reads as authentic. (The murder mystery plots aren't of the best, unfortunately.) What might be of particular interest to you, though, is 1588: A Calendar of Crime which contains five short stories set at each of five festivals during the one year – Candlemas, Whitsunday, Lammas, Martinmas and Yule with notes at the end giving full detail of the festivals and the year.
Speaking of notes, the Rory Clements book I mentioned gives an overview of the legal penalties attaching to Catholics during Elizabeth's reign, together with a transcript of the Catholic Spiritual Testament which John Shakespeare (father of Will) probably signed, which may be of interest.
Having said that, if you're setting the novel in a real time, even if not a real place, you might be better off finding a good non-fiction book rather than relying on another author for period detail, which could well be wrong.
