Katherine Solomon’s emergency call

Katherine Solomon’s emergency call turns her escape from Mal’akh into an attempt to bring help to two endangered places: the Smithsonian Museum Support Center and a mansion in Kalorama Heights where she believes her brother, Peter Solomon, is captive. The call also sets the course for her next move: unable to contact Robert Langdon, she drives toward the Library of Congress, then recognizes that the distant fireball is the destruction of her laboratory.

The Call and Its Two Destinations

From a pay phone at a gas station on Suitland Parkway in Anacostia, Katherine tells the Washington, D.C., dispatcher that she has been attacked at the Smithsonian Museum Support Center and asks for police to be sent there. She gives the address as 4210 Silver Hill Road, making the immediate request concrete even as she is still fleeing the danger.

She adds a second destination: a mansion in Kalorama Heights, where she thinks Peter may be held captive. The call therefore links the attack on her laboratory to the search for her brother, directing authorities toward both the scene she has escaped and the place where she fears he remains in danger. The dispatcher’s impatience contrasts with the urgency of Katherine’s warning; the call has to carry several emergencies at once.

What Katherine Knows

Katherine’s suspicion about the mansion rests on her belief that the attacker who killed her mother and nephew has now captured Peter and come after her. She knows that the man she encountered under another identity is connected to both the family’s past losses and the present threat, but the reason for his interest in a pyramid still makes little sense to her. Her call reports what she can act on—the locations and the people at risk—without resolving the larger mystery.

She also wants help for Trish Dunne, her assistant, whom she hopes police will find at the Smithsonian Museum Support Center. In this way, the call is not merely a plea for Katherine’s own safety: it asks authorities to check on Trish, investigate the intruder, and search for Peter. The separate requests reveal how quickly the danger has widened beyond the person making the call.

From Warning to Recognition

After the call, Katherine cannot obtain Robert Langdon’s unlisted cell-phone number. With no direct way to reach him, she drives toward the Library of Congress, where she understands he is headed. The choice keeps her moving toward a possible ally while the police pursue the locations she has reported.

A flash in her rearview mirror first registers as an unexplained light, but it grows into an orange fireball above the trees, accompanied by black smoke. Katherine recognizes that it is not distant entertainment or an unrelated industrial blaze: it is the explosion at the Smithsonian Museum Support Center, where Mal’akh has attacked her laboratory. The call’s warning thus becomes an account of a catastrophe already unfolding, and her realization connects the visible destruction to the danger she has just escaped.
