Shorea robusta, also known as sal or shala tree, is a species of tree belonging to the Dipterocarpaceae family.

This tree is native to the Indian Subcontinent, ranging south of the Himalaya, from Myanmar in the east to Nepal, India and Bangladesh. In Nepal, it is found mostly in the terai region from east to west, especially, in the Churia range (the Shivalik Hill Churia Range) in the subtropical climate zone. There are many protected areas, such as Chitwan National Park, Bardiya National Park Bardia National Park, Shukla Phat National Parks, etc., where there are dense forests of huge sal trees. It is also found in the lower belt of the hilly region and inner terai. In India, it extends from Assam, Bengal, Orissa and Jharkhand west to the Shivalik Hills in Haryana, east of the Yamuna. The range also extends through the Eastern Ghats and to the eastern Vindhya and Satpura ranges of central India. It is often the dominant tree in the forests where it occurs.

Sal is moderate to slow growing, and can attain heights of 30 to 35 m and a trunk diameter of up to 2-2.5 m. The leaves are 10–25 cm long and 5–15 cm broad. In wetter areas, it is evergreen; in drier areas, it is dry-season deciduous, shedding most of the leaves in between February to April, leafing out again in April and May.

In the Woods is a 2007 mystery novel by Tana French about a pair of Irish detectives and their investigation of the murder of a twelve year old girl. The novel won several awards such as the 2008 Edgar Award for Best First Novel By An American Author, the 2008 Barry Award for Best First Novel, the 2008 Macavity Award for Best First Mystery Novel, and the 2008 Anthony Award for Best First Novel.

Twenty years prior to the novel's events, twelve year-old Adam and his two best friends failed to come home after playing in the familiar woods bordering their Irish housing estate. A search is called by the families, and the police find Adam shivering, clawing the bark of a nearby tree, blood on his shoes and slash marks on his back. He is unable to tell them what happened or where his friends are. His amnesia holds to the present day, where he goes by his middle name, Rob, to avoid the attention of the media to his famous case. His friends were never found.

The plot of the novel circles around the murder of a twelve year old girl, Katy Devlin, whose case Rob and his partner Cassie Maddox are given to investigate. The body is found in the same woods where Rob’s friends disappeared, at an archeological dig site, and the coincidence is enough to make Rob nervous, though he insists to his partner that he is fine.
