The Winter Murder Case [EPUB ebook] 

“How would you like a brief vacation in ideal surroundings—winter sports, pleasing company, and a veritable mansion in which to relax? I have just such an invitation for you, Vance.”
Philo Vance drew on his cigarette and smiled. We had just arrived at District Attorney Markham’s office in answer to a facetious yet urgent call. Vance looked at him and sighed.
“I suspect you. Speak freely, my dear Rhadamanthus.”
“Old Carrington Rexon’s worried.”
“Ah!” Vance drawled. “No spontaneous goodness of heart in life. Sad. So, I’m asked to enjoy myself in the Berkshires only because Carrington Rexon’s worried. A detective on the premises would soothe his harassed spirits. I’m invited. Not flatterin’. No.”
“Don’t be cynical, Vance.”
