The Four Left-Handed Maidens and the Highwayman of London City in 1799 [EPUB ebook] 
An Investigation by Brock Adair, the Resident Detective of Ballymena, County Antrim, and Kitty Bradshaw Brennan, the Red-Headed Mistress of Disguise from Wexford

In 2006 a bundle of hand written pages were discovered buried in a garden in the outskirts of Cullybackey near Ballymena, County Antrim. They had been penned by Charles Kinhilt a lawyer from Cullybackey, County Antrim. They had been sealed in sacking and placed in a wooden box which had been covered in what appeared to be bitumen. The contents revealed the journal of one Brock Adair outlining his investigations into crime in County Antrim and indeed the whole of the island of Ireland in the late 1700s and into the 1800s. Further reading revealed a lady called Kitty Bradshaw Brennan from Wicklow who is believed to be Irelands first female investigator although this is not a proven fact .She and Brock conducted many successful enquiries together.
