Margaret Sinclair, a wealthy dowager and member of Dowling’s parish, dies suddenly and suspiciously, a full oxygen tank easily within her reach, her private nurse out of earshot. The owner of a collection of landscape paintings by a famous American artist, Sinclair herself appeared in one of the few portraits the artist ever painted. As the family squabbles over the contents of the will, it becomes clear to Father Dowling that neither the old woman’s life nor her death was ordinary. Then a second death occurs in the Sinclair mansion, and a tragic mystery from the old woman’s youthful honeymoon reemerges to affect her heirs. Both are somehow connected to the portraits, as Father Dowling probes for the truth about a complicated family.
