Report of Independent Registered Public
Accounting Firm

To the Board of Trustees of Deutsche Investment Trust
and Shareholders of Deutsche Large Cap Focus Growth
Fund:
In planning and performing our audit of the financial
statements of Deutsche Large Cap Focus Growth Fund
(the "Fund"), as of and for the year ended July 31, 2016, in
accordance with the standards of the Public Company
Accounting Oversight Board (United States), we
considered the Fund's internal control over financial
reporting, including control activities for safeguarding
securities, as a basis for designing our auditing procedures
for the purpose of expressing our opinion on the financial
statements and to comply with the requirements of Form
N-SAR, but not for the purpose of expressing an opinion
on the effectiveness of the Fund's internal control over
financial reporting.  Accordingly, we do not express an
opinion on the effectiveness of the Fund's internal control
over financial reporting.
The management of the Fund is responsible for
establishing and maintaining effective internal control
over financial reporting.  In fulfilling this responsibility,
estimates and judgments by management are required to
assess the expected benefits and related costs of controls.
A fund's internal control over financial reporting is a
process designed to provide reasonable assurance
regarding the reliability of financial reporting and the
preparation of financial statements for external purposes
in accordance with generally accepted accounting
principles.  A fund's internal control over financial
reporting includes those policies and procedures that (1)
pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and
dispositions of the assets of the fund; (2) provide
reasonable assurance that transactions are recorded as
necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles,
and that receipts and expenditures of the fund are being
made only in accordance with authorizations of
management and trustees of the fund; and (3)  provide
reasonable assurance regarding prevention or timely
detection of unauthorized acquisition, use or disposition
of a fund's assets that could have a material effect on the
financial statements.
Because of its inherent limitations, internal control over
financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of
effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in
conditions, or that the degree of compliance with the
policies or procedures may deteriorate.
A deficiency in internal control over financial reporting
exists when the design or operation of a control does not
allow management or employees, in the normal course of
performing their assigned functions, to prevent or detect
misstatements on a timely basis.  A material weakness is a
deficiency, or a combination of deficiencies, in internal
control over financial reporting, such that there is a
reasonable possibility that a material misstatement of the
Fund's annual or interim financial statements will not be
prevented or detected on a timely basis.
Our consideration of the Fund's internal control over
financial reporting was for the limited purpose described
in the first paragraph and would not necessarily disclose
all deficiencies in internal control over financial reporting
that might be material weaknesses under standards
established by the Public Company Accounting Oversight
Board (United States).  However, we noted no deficiencies
in the Fund's internal control over financial reporting and
its operation, including controls over safeguarding
securities, which we consider to be material weaknesses as
defined above as of July 31, 2016.
This report is intended solely for the information and use
of the Trustees, management, and the Securities and
Exchange Commission and is not intended to be and
should not be used by anyone other than these specified
parties.

EX-99.77D POLICIES

Item 77D Deutsche Large Cap Focus Growth
Fund (a series of Deutsche Investment
Trust)

Effective on or about October 3, 2016, the
Fund's principal investment strategy will be
amended to include the following:

Derivatives. Portfolio management generally may
use futures contracts, which are a type of derivative
(a contract whose value is based on, for example,
indices, currencies or securities), as a substitute for
direct investment in a particular asset class, to keep
cash on hand to meet shareholder redemptions or
other needs while maintaining exposure to the stock
market.

The fund may also use other types of derivatives (i)
for hedging purposes; (ii) for risk management; (iii)
for non-hedging purposes to seek to enhance
potential gains; or (iv) as a substitute for direct
investment in a particular asset class or to keep cash
on hand to meet shareholder redemptions.

EX-99.77E LEGAL

Item 77E - Deutsche Investment Trust (formerly
DWS Investment Trust)
On December 7, 2010, Deutsche Investment Trust
(formerly DWS Investment Trust) (the "Trust") was
named as a defendant in the First Amended
Complaint filed by the Official Committee of
Unsecured Creditors in the U.S. Bankruptcy Court
for the District of Delaware in the lawsuit styled
Official Committee of Unsecured Creditors of
Tribune Company, et al., v. Fitzsimons et al. (the
"Lawsuit").  The Lawsuit arises out of a leveraged
buyout transaction ("LBO") in 2007 by which loans
were made to the Tribune Company to fund the
LBO and shares of the Tribune Company held by
shareholders were tendered for or were converted to
a right to receive cash.  Following the completion of
the LBO in 2007, the Tribune Company filed for
bankruptcy.  The Lawsuit seeks to recover all
payments made to the shareholders in the LBO.
The Lawsuit has been consolidated in a multi-
district litigation in the United States District Court
for the Southern District of New York, case no. 12-
MC-2296.  At the outset of the Lawsuit, the Court
issued a scheduling order which stayed all
substantive proceedings in the Lawsuit until after
the decision on motions to dismiss based on certain
defenses common to the defendants filed in related
cases.  On September 23, 2013, the District Court
entered an order granting the defendants' motion to
dismiss in those related cases due to the pendency
of the Lawsuit seeking recoveries on similar
grounds, and the plaintiffs in the related cases have
appealed that order to the United States Court of
Appeals for the Second Circuit.  Oral arguments
were held in November 2014. On March 29, 2015,
the Second Circuit, in a unanimous opinion,
affirmed the District Court's dismissal of the related
cases.  The plaintiffs in the related cases
subsequently filed a petition for rehearing, which
the Second Circuit denied on July 22, 2016.
Accordingly, the Lawsuit will continue to seek
recovery of all amounts that the Trust received on a
theory of intentional fraudulent conveyance.  On
November 21, 2013, the District Court entered
Master Case Order No. 4 ("MCO 4") setting forth
the procedures to govern the Lawsuit and
effectively lifting the above-referenced stay. Among
other things, MCO 4 requires the parties to present
proposals for a structure to govern the upcoming
pre-answer motions to dismiss stage of the
Lawsuit.  On April 25, 2014, the District Court
entered an order governing the upcoming stage of
the Lawsuit, which directed Ropes & Gray, as
Liaison Counsel to the Shareholder Defendants, to
file a global motion to dismiss (the "Global Motion
to Dismiss") the Lawsuit on behalf of all
shareholder defendants named in Exhibit A to the
current Fifth Amended Complaint (including the
Trust).  Briefing of the Global Motion to Dismiss
has concluded, and the District Court has not yet
scheduled a date for oral argument.  The District
Court has also deferred all other proposed motions
to dismiss the Lawsuit, if necessary, until a later
date to be determined. Management is currently
assessing the Lawsuit and has not yet determined
the effect, if any, on any series of the Trust.
Deutsche S&P 500 Index Fund, the only fund in the
Trust that was the beneficial holder of shares of the
Tribune Company, has been reorganized into
Deutsche Institutional Funds and none of the
Trust's current funds have exposure in the litigation.
