Remnants of the Georgian era and the dawn of the 19th Century. Alienist Williams Stalker falls from grace and is banished to the penal colony Barbados to serve as an indentured servant. Born in Scotland a mulatto, his bi-racial skin colour led to experiences of scorn, colourism and racism in England where he migrated with his mother. Sent to the colony, he then discovers an essential root in his family tree and witnesses the horrors of slavery. A contemporary tale, it travels through southern England to beautiful Barbados, its world heritage sites, the historic Garrison, the subterranean tunnels beneath it and the mysterious burial vault. Married to the beach colonialist the tiny island was called a precious jewel in the British crown. The Vault infolds a story of love, mystery, and the evil machinations of slavery in the West Indies during the transatlantic slave trade.
