The world’s most unlikely crime solving duo is back – and this time Irish nun Sister Agatha Murphy and Indian hotel owner Avtar Mehta discover that family secrets are the most deadly.

When the tyrannical head of one of Delhi’s richest families is found dead inside a locked room within the historic Elephant House, Sister Agnes and Avtar must solve an impossible murder.

All the children have motives, but would any of them really kill their mother for her money? Or is her death payback for a much deeper debt?

As the city builds bonfires to celebrate the festival of Lohri, Sister Agatha and Avtar face backstabbing siblings, a gangster with untold influence, a police siege and a cigarette-stealing elephant. Avtar and Sister Agatha are on the hunt for a murderer, but is someone pulling their strings? When a killer is prepared to do the unthinkable, no one is safe and no one can be trusted.
