Marco Malvaldi is an Italian chemist and novelist, who began his writing career in 2007 with his first mystery story La briscola in cinque (Game for Five, 2014), published by the Italian Sellerio Editore and featuring Massimo, the barista and owner of the cleverly named BarLume ("Bar Light", also a wordplay for "flicker, glimmer of light") who is forced into the role of investigator in the fictional seaside resort town of Pineta, along the Tuscan coast.

Three-card Monte, 2014), Il re dei giochi (The King of Games) (2010), La carta più alta (The Highest Card) (2012).
