Nihal has chosen Amma, the debut novel by Sri Lankan writer Saraid de Silva, which he compares to meeting someone on a train and having a long, intense conversation. Elif Shafak's choice, however, You're Embarrassing Yourself by Desiree Akhavan, he describes as more like a hilarious night in a pub. Harriett has gone for The Second Murderer by Denise Mina, a Philip Marlowe novel. But is there a need to add to Raymond Chandler's canon?
