In Fortune (a novel by Bruce Weiss)

A middle-aged man named Jakedown, on his luck, just divorced, and facing job loss, finds himself a fugitive. Seized from the wreckage of his old life, however, is one meaningful memento, one with the power to reignite his interest in life, but one that sets him on a dangerous journey that he could never have imagined.

Jake has retrieved an old diary written by someone whom he believes to be his grandmother, a sixteen-year-old Irish girl named Jenny, who was forced to emigrate alone to America in 1914 before disappearing. In the binding of the diary, Jenny has left a key to her home in Ireland and the key to a great mystery. The key will not only unlock a door but also troubles that are more than he could never have imagined.

A story of international intrigue, menace, and murder, not to mention a fast-paced and compelling novel with well-portrayed characters, this is a riveting read.
