A Most Peculiar Circumstance (Ladies of Distinction #2)
Jen Turano

Mr. Theodore Wilder, private investigator extraordinaire, is on a mission. A mission that began as a favor to his good friend Hamilton Beckett, but swiftly evolved into a merry chase across the country. By the time he finally tracks down Hamilton's sister, Arabella, he is in a less than pleasant mood. When the lady turns out to have radical ideas and a fiercely independent streak, he soon finds himself at his wit's end.
When they return home to New York, circumstances force their paths to continue to cross, but the most peculiar feelings growing between them certainly can't be love. When the trouble Arabella had accidentally stirred up seems to have followed her to New York and threatens her very life, the unlikely couple must face the possibility that they might have landed in the most peculiar circumstance of all: love.
