The Scandal of Lady Eleanor

James Kerrington, a key member of the British government's secret unit, the Realm, never expected to find love again after the loss of his beloved wife. But a visit to his close friends, the Thornhills, leads to a chance meeting with Lady Eleanor Fowler.
Instantly Kerrington's whole world tilts on its axis.

THE DEBAUCHERY OF LORD THORNHILL
For years, Lady Eleanor hid from Society, knowing her father's
notorious reputation for wickedness tainted her chance for
romantic fulfillment. Now with Kerrington's advances and
her father's recent death, she is at last hopeful that her family's
dark past is behind her. But when Sir Louis Levering appears
with final proof of her father's depravity, Eleanor is drawn into
a web of immorality and blackmail.

RETURN OF THE REALM
To free Eleanor from Levering's diabolical clutches, Kerrington
brings together his former Realm comrades. Before they can
save her, they must confront their own secret pasts and tangle
with Shaheed Mir, a longtime nemesis who is exacting revenge
against members of the Realm for stealing a mysterious emerald
from his homeland. -- Goodreads
