The Times (London):
"Not for nothing is Claudia Piñeiro Argentina's most popular crime writer. Betty Boo is original, witty and hugely entertaining; it mixes murder with love, political power and journalism. Delightful characters include a morose veteran hack and a young trainee known only as Crime Boy. Iscar falls in love and the homicide count has moved up the ladder of Argentine politicians."
Booklist:
"Those willing to take the time to enjoy the style and the unusual denouement will find themselves wondering why more crime authors don't take the kinds of risks Piñeiro does."
Publishers Weekly:
"At the start of this thought-provoking mystery from Piñeiro (A Crack in the Wall), maid Gladys Verela arrives at the Maravillosa Country Club, where industrialist Pedro Chazaretta has a house on the grounds. In the living room, Gladys spots Chazaretta sitting in a chair, apparently asleep, but in fact his throat has been slit. In Piñeiro's artful hands, each of her investigators learns as much about himself or herself as about the murder on the way to the surprising, perfectly executed ending."
Book Riot:
"Piñeiro is AWESOME. Her books are dark, have buckets of atmosphere, and they all feel entirely different even though she revisits some of the same issues again and again. She deals with the culture and social structure within gated communities; shows how walling ourselves in seems safer, but actually promotes fear and claustrophobia; she deals with gender roles and prejudice and economic class and long-held secrets that fester."
