On Monday morning, Jess arrived at the office and put her phone on her desk. Then she went to make a cup of tea. When she came back, the phone was gone.
"Has anyone seen my phone?" she asked. Nobody had seen it.
Jess looked under her desk, in her bag and in her coat. Nothing. She was starting to panic. All her photos were on that phone.
Her colleague Ben decided to help. "Let's be detectives," he said. "Who was near your desk?"
Jess thought for a moment. "Mr Patel walked past to the printer. And Lily from marketing came to borrow a pen."
