Gretta Mulrooney’s standalone novels predate her crime fiction career and show a different side of her writing. The early titles, A Can of Worms (1993), A Nest of Vipers (1994), and A Den of Thieves (1995), form an informal trio with their animal-metaphor titles. Araby (1998) and Marble Heart (2000) are more personal literary novels drawing on her Irish heritage.
Her later standalones include Fire and Ice (2006), Out of The Blue (2007), The Apple of Her Eye (2010), Walking on Water (2014), My Own Sweet Way (2015), Lost Child (2016), and Coming of Age (2016). These books explore themes of family, identity, and memory with the same attention to character that she later brought to her crime fiction.
