William L. Biersach was born in Pasadena, California, on the Feast Day of St. Philip Neri, the “Laughing Saint”, in 1953. A product of Catholic grammar and high school, he naturally lost his Faith when the effects of Vatican II came rattling through the world like a maniacal jalopy in the 1960's and 70's. He found his way back to Traditional Rome in 1993 and has been active in trying to reacquaint Catholics with their own religion ever since.

The Endless Knot is the first of his Father Baptist novels. He is currently working on the rough draft for the sixth book in the series. He resides in a stone house somewhere in Southern California, likes spicy food, and hopes to retire in Heaven some day.

William Biersach and Charles Coulombe regularly hold Catholic Tradition talks at 7:30 PM on the second Friday of every month at St. Therese's Church in Alhambra. For more information, click here. These talks are designed to inform and entertain. You can find and listen to these talks either on the Tumblar House Youtube Channel or you can download them for free here.

Reviews of William L. Biersach's Novels:

William Biersach's character of Fr. John Baptist is a rare commodity: he's a real man's man; the kind who used to flock to the priesthood because the greatest opponent a man could face was supreme evil, the greatest battle to be won was the salvation of souls.

Professor Biersach's Father Baptist mysteries are proof that supernatural evil still needs to be exorcized in traditional fashion. It can't continue to be swept under the chair (or cathedral). The Search for Saint Valeria, the third in the series, promises to take us deeper beneath the darkened conscience of the post-conciliar American Church. As Father Baptist and Martin Feeney confront the darkness, Biersach makes us shudder in horror and laugh out loud in recognition. And there are a lot of good laughs to be had.

I read literally all night, my heart pounding with anticipation, fear or excitement, turning pages almost faster than I could read. I read all the next day, and into the night as well, having cooked no meals for the family, ignored the laundry, the telephone, the computer and everything else! Before purchasing The Endless Knot or The Darkness Did Not, do take the time to at least buy TV dinners and arrange for a babysitter! Then guilt free inhale some of the best mystery stories ever written!

If you never thought you could howl with laughter while sheer terror stands your hair on end, read this book!

The Darkness Did Not: It's better than broccoli!

Sherlock Holmes and Dr. Watson, Hercule Poirot and Hastings move over! Fr. John Baptist and his chronicler, Martin Feeney, are every bit as endearing as their better-known counterparts. The characters are well-drawn. You'll come to think of them as friends. The plots are fascinating, the events cathartic, and you've given an inside view of the world of radical traditional (rad/trad) Catholicism. I simply couldn't put them down until I had read each one twice!

I just love Mr. Biersach's books. They combine all my favorite things: the Catholic faith, murder mystery, and laughter. As a matter of fact I have laughed so hard in some places it brought tears to my eyes. I will admit I have even underlined parts I didn't want to forget.

William Biersach gives a whole new meaning to working out one's salvation in fear and trembling.

P.S. Comment from my 17 year old daughter, Bernadette: Don't read TDDN at night! And from our 14 year old son, Stephan, budding writer and aspirant to the Knights Tumblar: Mr. Biersach has written books of light and truth, and the darkness will not comprehend it.


Not just for Catholics. William Biersach's mystery novels will crowd right to the top of anyone's Favorites list! A tip: Don't pass these books around. You'll never get them back!

Biersach creates a unique mystery plot, incorporates long-forgotten spiritual forces, fine tunes his character development, humorously exploits the Novus Ordo antics of the modern Church, while he simultaneously remains theologically correct. Pure genius!

Just when we thought we had it, there was another twist. The characters are so real that we think we know them. With about thirty books on the shelf to be read right now, I could not put The Endless Knot down! Still checking it because more details come to light with each reading. Underlined the first novel ever. MORE! MORE! I'm beggin' for MORE, ya hear?

What a wonderful group of characters! Biersach brings each of them to life in uncanny detail. You'll find yourself wanting to drive down to St. Philomena's to watch it all in person. It's hard to shake the belief that they're really there. A word of caution: you'll want to stock up on plenty of freezer dinners and make sure the laundry's done before you open this book because the rest of the family will have to fend for themselves until the last page is read. I can't remember the last time I've enjoyed a book this much.

William Biersach is doing exactly what needs to done to reintroduce our culture to faith and truth. This is another style of evangelization that will work very well in our times.

When's the last time you read a book where the characters think and believe as you do? I purchased multiple copies, and yesterday my husband and two sons were reading the whole time they were in the house. No sports. No TV. Yippee! We are all having the best time together, so much fun to have someone start laughing, or pensively announce "Listen to this!" and read a passage or prayer. Thank you for some wonderful family time.

P.S. By the way, Chisum was irritated that I interrupted his straight-through reading of King's Dark Towers series to make him sit down with The Endless Knot. Just five chapters, Honey, then you can put it down. However, when I got up this morning, I found he'd not only finished The Endless Knot, but started The Darkness Did Not unbidden!


I find myself referring back to The Endless Knot regularly, and it is the only novel I own that I have underlined. Biersach's eloquent explanation of the faith required not to believe in the authenticity of the Shroud of Turin is worth the price of the book by itself.
