Return to the Greek islands in The Blue Door of Santorini, a witty 1950s historical mystery filled with secrets, rumors, and romance.

A door that opens onto a room is ordinary.

A door that opens onto nothing is considerably more interesting.

At the beginning of The Blue Door of Santorini, Lulu Penrose is looking across the cliffs when she notices a striking blue door set into a house high above the sea.

The door appears to lead nowhere.

Naturally, Lulu would like to know why.

This is precisely the sort of curiosity that made her first Mediterranean holiday rather more complicated than expected. It is also what draws her into the second mystery of the Doorway Series.

Returning to Santorini

Set in 1953, The Blue Door of Santorini brings Lulu, Mrs. Dalrymple and Stuart back to the dramatic beauty of the Greek islands.

Santorini offers whitewashed houses, blue-domed churches, winding paths and astonishing views over the Aegean Sea. It also offers an influential local family, a long-standing feud and rumors that refuse to remain politely in the past.

At the center of the mystery is the Kallistrate family, a wealthy shipping family with an impressive home and a history that continues to attract speculation.

Years earlier, smuggling had taken place in the region. That activity is believed to have ended—but island rumors suggest that someone may have revived it.

The evidence is uncertain.

The gossip is not.

Rumors, Secrets and Unhelpful Enthusiasm

A private family disagreement is overheard. The story passes from one person to another, collecting new details as it travels.

By the time the rumor reaches the wider island, an ordinary explanation has become a full criminal enterprise.

This would be troublesome enough without the involvement of several overly enthusiastic fortune-seekers who become convinced that hidden goods are waiting to be intercepted.

Their attempts to uncover the supposed smuggling operation repeatedly collide with secret meetings, family tension and Lulu’s own investigation.

Everyone is watching someone.

Very few people understand what they are seeing.

Lulu gradually realizes that the mystery may depend less on what has happened than on how the story has been told. A glance, a reprimand or a meeting after dark can appear deeply suspicious when separated from its true explanation.

Unfortunately, discovering that explanation requires Lulu to venture closer to the blue door and the family behind it.

A Mystery About What People Choose to Believe

While The Pink Door of Positano introduces the characters and the wider world of the series, The Blue Door of Santorini explores the damage—and occasional absurdity—that can result when speculation becomes accepted as fact.

The novel still includes the ingredients readers can expect throughout the Doorway Series: a beautiful historical setting, an intriguing mystery, humorous complications and plenty of conversation over food and drink.

It also continues Lulu’s evolving relationship with Stuart.

Their feelings are becoming harder to overlook, although both remain remarkably skilled at doing exactly that.

Stuart would prefer Lulu to avoid danger.

Lulu would prefer Stuart to stop assuming he may tell her what to do.

This arrangement works about as well as one might expect.

Mrs. Dalrymple watches their progress with the patience of a woman who recognizes that some conclusions must be reached without outside assistance, no matter how painfully long it takes.

The Second Door Opens Wider

The Blue Door of Santorini can be enjoyed for its individual mystery, but it also deepens the friendships and romantic threads established in the first book.

The island setting is both beautiful and dramatic, providing the perfect place for old grudges, family loyalties and secret meetings to become tangled together.

For readers who enjoy Greek island mysteries, lighthearted historical fiction and slow-burn romance, this second Doorway adventure offers another escape into the Mediterranean—along with a reminder that rumors are rarely improved by repetition.

And that a door leading nowhere may still lead directly into trouble.
