Mercer’s Law
A Spectral Detective mystery
By C.J. Charles
Mercer’s Law
Washington, D.C., August 1945.
The war is ending, but Detective Sam Mercer has a mystery on his hands.
A woman has disappeared from a Columbia Heights boarding house, leaving behind her clothes, her luggage, a substantial amount of cash—and documents bearing more than one name.
Mercer has dealt with grifters before. False identities, forged papers and invented lives are nothing new. As the Baird said, …the world's a stage, And all the men and women merely players.
Mercer’s routine missing-person case unravels. The War might be as good as over, but dark forces are still fighting.
Pulled into line by veteran detective Walter Hennessy, Mercer meets a former OSS operative Arthur King, blinded on a mission earlier in that year.
Mercer has a law about coincidences:
One happens. Two deserve attention. Three probably aren’t.
