He Said the Cast Was Healing—Until His Mother Found the Needle

Chapter 02 - The Signature Under Sedation

At Saint Catherine’s Children’s Hospital, toxicology results arrived at 2:13 in the morning.

Mateo’s blood contained a powerful sedative, an antipsychotic medication, and an opioid concentration inconsistent with the prescription Lydia entered into his chart. None of the doses were immediately fatal. Together, they could cause confusion, memory gaps, slowed speech, and emotional outbursts.

The exact symptoms Adrian had been telling everyone Mateo developed after his father’s death.

Dr. Priya Shah, the emergency pediatrician, photographed the device removed from the cast. Its small reservoir carried the logo of Northbridge Medical Systems, Adrian’s company. The serial number had been scratched away.

“This is not a normal pain pump,” she said. “It is a prototype micro-infusion port.”

Elena stared through the glass at Mateo sleeping beneath a warmed blanket.

“How long was it delivering medication?”

“Possibly the entire time he wore the cast.”

“Ten days.”

Dr. Shah did not soften her expression. “His fracture is not ten days old. Based on the healing response, it occurred about four days ago.”

Elena remembered the timeline.

Ten days earlier, Adrian announced that Mateo fell from a tree while visiting Lydia’s private clinic. He brought the boy home already casted and heavily drowsy. Elena was not allowed into the treatment room because Lydia claimed Mateo became distressed when his mother cried.

For six days, her son had worn a cast over an arm that was not yet broken.

“What was inside it before the fracture?” Elena asked.

Dr. Shah looked at the puncture pattern beneath the padding.

“The same line.”

The first cast had been placed to administer drugs. When Mateo later discovered the hidden files and tried to escape, Adrian broke his arm. Lydia replaced the cast and continued the infusion, making the real injury resemble the original story.

A hospital social worker asked Elena to sign emergency protection papers.

Her hand stopped over the final page.

The signature already in Mateo’s Northbridge medical file looked like hers.

It was not.

Lydia had copied Elena’s name onto the consent form.

Detective Dana Brooks arrived with two child-protection investigators. She listened without interruption, then asked whether Adrian had access to Mateo’s inheritance.

Elena hesitated.

Daniel Marlowe, Mateo’s biological father, had founded Northbridge with Adrian. After Daniel died in a warehouse explosion, his shares entered a trust for Mateo. Adrian managed the company until the boy turned twenty-five.

“But if Mateo is declared permanently impaired,” Elena said slowly, “the trustee can convert his shares into a guardianship holding.”

“Who becomes guardian?”

Elena looked at the forged consent.

“Adrian.”

Her phone lit up.
