The Delaware Valley Chapter of Sisters in Crime (DVSinC) mystery / crime writers and readers group (serving the Philadelphia area, southern New Jersey, and Delaware) meets once a month from January through May and from September through December. Each meeting is held on the third Saturday of the month from 9:30 a.m. until noon. Meetings are held at the Tredyffrin Public Library, 582 Upper Gulph Road, Strafford, PA 19087, in the first-floor meeting room, directly inside the front entrance to the library. For directions to the library, please go to our Directions page.




2019 Meeting Dates: January 19; February 16; March 16; April 20; May (picnic for members only); September 21; October 19; November 16; December (holiday party for members only).

On occasion, we will schedule a field trip in place of a regular meeting. Field trip details will be announced on our Home page at least one month in advance. While our regular meetings are open to anyone who wishes to attend, our field trips, picnic, and holiday party are open to DVSinC members, only. Past field trips have included trips to a morgue; an historical graveyard; the Mutter Museum; the Winterthur Museum; the University of Pennsylvania Veterinary School, New Bolton Campus; a 911 call center; and a police station.


Our mingle-and-book-browsing session begins at 9:30 a.m. To raise a bit of extra money for our coffers, we ask members to donate mysteries they have already read, and then we resell them at a nominal fee. We are prolific readers, so there are always many books from which to choose.

Our main session begins at approximately 9:45 a.m. and includes a business meeting, a “mentoring” session, during which we discuss some aspect of the writing craft, and a guest speaker from outside the group.

Our guest speakers offer insight into various occupations and procedures that are as interesting to our reader-members as they are to our writers. In the past, we have had the privilege of welcoming judges, forensic anthropologists, coroners, fire investigators, cyber-crime sleuths, FBI agents, and all manner of fascinating guest speakers. Our speakers engage in lively discussions with our members and guests and often join us for lunch following the meeting.

The meeting adjourns at noon, when we invariably go out for lunch at a local restaurant. Anyone who attends a meeting is welcome and encouraged to join us.

Please note: The activities of DVSinC are not sponsored by the Tredyffrin Public Library.
